30-piece motorcycle engine screw cap set in ABS plastic with eight colour options

This comprehensive 30-piece set of motorcycle screw caps offers a practical finishing solution for engine bay modifications. Each cap is manufactured from ABS plastic, providing protection for exposed engine bolts while allowing for colour customisation. With eight distinct colours available – black, red, gold, blue, silver, green, orange, and purple – riders can match their bike's existing scheme or create accent highlights. The caps install with a simple press-fit method, requiring no specialised tools, making them accessible for motorcycle enthusiasts performing their own modifications.
Features and Construction

This screw cap set is designed specifically for motorcycle engine applications, with thirty individual pieces providing coverage for multiple bolt points. The construction focuses on practical functionality for engine bay environments where protection and aesthetics combine.
Material and Build
Each screw cap is made from ABS plastic, a thermoplastic polymer known for its chemical resistance and durability in automotive contexts. This material choice makes the caps lightweight while offering protection against common engine bay substances. The plastic construction allows for consistent colour throughout each piece without painting or finishing required.
Size and Practical Fit
The set includes thirty identical screw caps designed to cover standard motorcycle engine bolts. While exact dimensions aren't specified in the product information, the press-fit installation method indicates they're engineered to fit securely over exposed bolt ends. The quantity allows for comprehensive coverage of multiple engine bay points during modification projects.
Uses and Placement

These screw caps serve both protective and aesthetic functions in motorcycle applications. Their primary use is in engine bay areas where bolt ends become exposed during modification work or where factory finishes leave bolts unprotected.
Event or Professional Use
For motorcycle shows or professional builds, the eight colour options allow for precise colour matching or intentional contrast within custom engine bays. The complete 30-piece set ensures sufficient coverage for complex engine modifications where multiple bolt points require protection. The uniform appearance creates a finished, professional look.
Everyday Home Use
For home motorcycle maintenance and modification, these screw caps provide a straightforward solution for improving engine bay appearance and protecting bolt threads from dirt and corrosion. The simple press-fit installation makes them accessible for enthusiasts without specialised tools or skills. The colour variety allows riders to personalise their motorcycles according to preference.
Benefits and Buying Value

This product offers practical advantages for motorcycle owners seeking to improve their engine bay's appearance and protection. The value comes from both the comprehensive quantity and the colour selection options provided in a single purchase.
Reuse and Low Maintenance
The ABS plastic construction means the screw caps can be removed and reinstalled if needed during future maintenance work. Their chemical resistance reduces maintenance requirements in engine bay environments where oils, fuels, and cleaning products are present. The caps provide lasting protection without requiring regular replacement under normal use conditions.
Why Choose This Product
This set stands out through its combination of quantity and colour options – thirty pieces across eight colours provides flexibility for various motorcycle modification projects. The specific motorcycle engine modification focus ensures appropriate material selection and design for this application. Compared to purchasing individual caps, the set approach offers better value and ensures colour consistency across all protected bolts.
