M10 dome cap nuts in bright zinc plated steel deliver a snug, protected finish over exposed threads. Dome profile reduces snagging and helps protect surfaces and hands while remaining simple to fit.


Secure, low-profile finish – with dome cap design

Dome cap covers the nut and exposed threads, seating over the threaded end to create a smooth outer surface that conceals sharp edges. The cap geometry seats evenly to produce a consistent finish across assemblies.

Prevents snagging on clothing or fabric and keeps fingers safe from sharp threads. Ideal for knobs, wheels and visible fittings where a tidy appearance matters.

Fast, tool-friendly fitting – with standard M10 sizing

M10 thread size matches common bolts and knobs so nuts seat quickly and accept basic tightening methods; user feedback notes no special tools are required. Bright zinc plating does not alter the sizing or fit.

Speeds up assembly and repair tasks by allowing quick hand or simple-tool tightening. Suits repeated use in workshop and hobby environments.

Protects surfaces and hands – with rounded dome cap profile

Rounded cap encloses sharp threads and spreads contact across a larger area, reducing point pressure and abrasion. The enclosed design limits direct thread contact with other surfaces.

Keeps drawer contents and delicate finishes safe and reduces the risk of cuts during handling. Useful where exposed threads would otherwise scratch or snag.
