Black matte 17 mm screw caps, set of 20 pieces with key – No name

Set of 20 black matte screw caps designed for external 17 mm hex heads, supplied with a dedicated installation and removal key. These protective caps cover wheel or body fasteners to reduce exposure to dirt and corrosion while creating a uniform, low-gloss finish. The caps are intended for applications where an external 17 mm hex fits; check material compatibility and exact fit before installation to ensure proper protection and secure seating.

Advantages

Black matte finish provides a discreet, non-reflective appearance that integrates with many vehicle and equipment styles. The set includes a keyed tool that simplifies installation and removal, minimizing the risk of damaging fastener heads. By covering fasteners, the caps help limit ingress of grime and moisture, which can extend the service life of exposed bolts and nuts. Supplied in a pack of 20 to cover multiple mounting points or spare needs.

Suitable for

• Automotive wheel nuts and body fasteners with external 17 mm hex heads
• Light industrial machinery and equipment with exposed 17 mm hex fasteners
• Aesthetic finishing on visible bolts and nuts to achieve a uniform look

Key specifications

• Quantity: 20 screw caps plus one installation/removal key
• External hex compatibility: 17 mm
• Finish: black matte
• Intended use: protective cover for external hex-head fasteners

How to use

Before fitting, verify that the fastener head is an external 17 mm hex and that the cap material is suitable for the operating environment. Fit the cap over the fastener head by aligning it and using the supplied key to push or snap it into place until it seats securely. To remove, insert the key and pull or twist as required to disengage the cap without damaging the fastener. Inspect seating after installation and periodically check for tightness or damage, replacing any caps that show cracking or deformation.

Usage recommendations

Do not use these caps on fasteners that require routine torque checks unless removal is planned, and avoid installation on fasteners subjected to very high temperatures or chemical exposure without confirming material compatibility. For wheel applications, ensure caps do not interfere with wheel maintenance procedures and confirm clearance with wheel covers or hub accessories.
