Motorcycle Windshield Rubber Brass Well Nut Fasteners: Pack of 10 in M4, M5, and M6 Sizes

Upgrading or repairing a motorcycle windshield requires hardware that can withstand constant vibration while maintaining a secure, sealed fit. These rubber brass well nut fasteners are designed specifically for this application, combining a flexible rubber expansion sleeve with a durable brass nut insert. Supplied in a convenient pack of ten pieces, they offer a practical solution for a single repair project or a small custom fabrication job. The fasteners are available in three common metric thread sizes – M4, M5, and M6 – and feature a uniform black finish, making them a discreet and functional choice for motorcycle bodywork.

Features and Construction

This pack contains specialised riveting fasteners that utilise a two-part construction to create a reliable mounting point in sheet materials like plastic or fibreglass, common in motorcycle fairings and windshields.

Material and Build

Each fastener is built from two key materials: a rubber expansion sleeve and a brass nut insert. The rubber sleeve compresses when the brass nut is tightened, expanding radially to grip the sides of the mounting hole securely. This design helps create a vibration-dampening effect and can provide a degree of water sealing. The brass nut offers a strong, corrosion-resistant threaded anchor point for bolts. The entire assembly is finished in black.

Size and Practical Fit

The product is offered in three specific size variants to match different bolt diameters. The M4 variant has a stated size of 11mm, the M5 is 12mm, and the M6 is 13mm by 13.6mm. It is important to match the fastener size to both the bolt being used and the diameter of the pre-drilled hole in your motorcycle's windshield or body panel to ensure a proper, tight fit.

Uses and Placement

These fasteners are designed for scenarios where a robust, rattle-proof connection is needed on a vehicle subject to constant movement and vibration.

Event or Professional Use

For motorcycle mechanics, custom bike builders, or race team technicians, these well nuts provide a reliable, reusable fastening method for attaching windshields, fairings, or accessory mounts. Having a pack of ten on hand covers multiple attachment points on a single bike or allows for spares during a build. The availability of three thread sizes in one listing simplifies inventory for workshops dealing with various motorcycle models.

Everyday Home Use

For the motorcycle enthusiast performing their own maintenance or modifications, this ten-piece pack is a convenient solution. It is suitable for re-securing a loose OEM windshield, installing an aftermarket screen, or mounting small accessories like GPS brackets or camera mounts to bodywork. The installation process is straightforward, typically requiring only a socket or spanner to tighten the brass nut.

Benefits and Buying Value

Choosing this specific fastening solution over standard nuts and bolts offers distinct practical advantages for motorcycle applications.

Reuse and Low Maintenance

The rubber well nut design is generally reusable if removed carefully, allowing for panel removal during future maintenance without destroying the fastener. The brass nut resists corrosion better than standard steel in exposed conditions, contributing to a longer service life with minimal upkeep. The vibration-dampening property of the rubber can reduce the frequency of re-tightening checks.

Why Choose This Product

This product provides a targeted solution for a common motorcycle need. The pack of ten offers better value and convenience than buying individual fasteners, and the inclusion of three thread sizes adds versatility. The specification is clear and factual, listing the exact dimensions and materials, allowing you to confirm compatibility with your project before purchase. It addresses the specific problem of securing components on a vibrating platform without resorting to permanent adhesives or more complex rivet systems.
