Traditional bolts and nuts often require access to the rear of the panel, which isn't always possible with complex bike bodywork. This set of ten black well nut riveting fasteners provides a practical solution. Each unit combines a rubber expansion sleeve with a brass threaded insert, creating a robust fixing point directly within a single drilled hole. The set includes three common metric thread sizes—M4, M5, and M6—offering versatility for different bolt diameters used in motorcycle fabrication. The black finish and rubber construction help with weather sealing and vibration damping, while the brass nuts resist corrosion for long-term reliability in typical riding conditions.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/309ad757-e275-4784-a7e7-0dbeabe316e5.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThese fasteners are engineered for applications where a traditional nut and bolt assembly is impractical. Their design allows for installation from one side only, making them ideal for enclosed spaces or complex motorcycle frames.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eEach fastener is a two-part assembly. The main body is a black rubber sleeve designed to expand when the mating bolt is tightened. This expansion creates a secure, compressive grip on the walls of the mounting hole. Integrated into one end of this rubber sleeve is the second component: a brass nut. This brass insert provides the female thread for the bolt. The use of brass offers improved resistance to corrosion and seizing compared to standard steel, which is beneficial for hardware exposed to the elements on a motorcycle. The construction is simple yet effective, relying on mechanical expansion rather than adhesive or welding.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe set includes fasteners in three specific sizes, each with a corresponding product code. The G388150 variant features an M4 brass thread and has an 11mm size specification. The G388151 variant has an M5 brass thread and a 12mm size. The G388152 variant is the largest, with an M6 brass thread and dimensions of 13mm by 13.6mm. It is important to drill the mounting hole to the precise diameter recommended for the specific well nut size to ensure the rubber sleeve can expand correctly and create a firm, rattle-free hold. These dimensions cater to a range of common bolt sizes used in motorcycle accessory mounting.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/3b0fe2dc-79c1-43a8-8bb1-8078ffd74725.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe primary application for these fasteners is in the motorcycle modification and customisation scene. They solve a common problem faced by riders and mechanics when adding parts that weren't originally designed for the bike.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eFor professional workshops or individuals building custom bikes, show bikes, or undertaking significant fabrication work, these well nuts are a valuable hardware item. They allow for the neat installation of one-off panels, custom windscreens, or fabricated fairings without the need for complex bracketry or welding studs onto delicate parts. The ability to install them from the front side only significantly speeds up the fitting process for complex assemblies. The vibration-damping characteristic of the rubber component is also a benefit for parts subject to engine or road vibrations, helping to prevent fatigue cracking in panels.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor the home mechanic or enthusiast performing simpler modifications, this ten-piece set is equally useful. Common projects include securely mounting a new aftermarket windscreen to existing brackets, attaching small accessory panels or covers, or even securing electronic components like gauge clusters or switch housings inside fairings. The mixed sizes mean you are likely to have the correct fastener for the job, whether you're using smaller M4 bolts for lightweight plastics or sturdier M6 bolts for larger screens. Having spares is also advantageous for trial fittings or future projects.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/59ba9344-4d13-4b45-9b8d-02b3d911cef6.webp\"\u003e\u003c\/div\u003e\u003cp\u003eChoosing this specific fastener set offers several clear advantages over alternative mounting methods or purchasing individual sizes separately.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eWhile designed as a semi-permanent fastener, well nuts can often be removed and reused if done carefully, unlike solid rivets. If removal is necessary, simply unscrewing the bolt typically allows the rubber sleeve to relax, enabling the unit to be pulled out from the front. The brass threads are less prone to cross-threading or corrosion-seizing than cheaper materials, supporting easier disassembly if needed for maintenance or part replacement. The rubber itself is resilient and can maintain its sealing and gripping properties over multiple cycles if not overly stressed.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eThis product stands out for its focused application and completeness. It provides a ready-made solution for motorcycle modification needs with a sensible quantity and size range. Instead of sourcing individual well nuts from generic hardware supplies that may not offer brass threads or the correct size profile, this set is tailored. The inclusion of three part-numbered variants (G388150, G388151, G388152) covers the most frequently required thread sizes. For anyone working on bike customisation, having these on hand saves time and ensures a professional-looking, secure result for mounting panels and windshields where traditional nuts and bolts fall short.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/7f64d2b5-6dde-4bb6-9565-868d72bb34bc.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/8afd2281-faa7-4b13-86d5-71087aeef7a7.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/8d06ad83-e242-4a68-b54d-29fb5d784f54.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/90124ff3-27b3-4d9e-9cce-a92b053ab1a9.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/9e69cd02-035c-418b-acba-289de5181cf9.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/e09e9c56-3b34-4b5f-af7f-b560be706715.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black motorcycle well nut fasteners with brass threads in M4, M5, and M6 sizes for panel mounting.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/545\/2025-10-02\/original-image\/f25c6d48-da59-47ad-90c2-8335c72020fb.webp\"\u003e\u003c\/div\u003e","brand":"fcm1e0-ws","offers":[{"title":"M5","offer_id":52923289141584,"sku":"CJYD182713302BY","price":12.98,"currency_code":"GBP","in_stock":true},{"title":"M6","offer_id":52923289174352,"sku":"CJYD182713303CX","price":12.98,"currency_code":"GBP","in_stock":true},{"title":"M4","offer_id":52923289207120,"sku":"CJYD182713301AZ","price":12.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/9440\/3664\/files\/25d39d92-d6f6-4623-b024-2111860e1ab3.webp?v=1776571862","url":"https:\/\/xkkman.com\/products\/motorcycle-modified-windshield-rubber-nut-brass-nut-expansion-rubber-well-nut-riveting-fasteners-set-of-10-pieces-in-black-with-m4-m5-m6-brass-thread-insert-sizes-for-custom-motorbike-fairing-screen-and-accessory-panel-mounting","provider":"xkkman.com","version":"1.0","type":"link"}
