Small part, quiet confidence

A lean line, a flush face, and a decisive turn of an Allen key.

Under the surface

The bolt you notice only when it’s missing

Titanium, pared back

Hardware shouldn’t shout. The M5 x .8 x 40mm Titanium Countersunk Bolt settles in flush, letting clean planes and careful joins stay uninterrupted. GR5 titanium keeps weight down and resists the wear of damp garages, salty air, and daily handling. Multiple finishes—from polished to oil slick—let function match the tone of the build without compromise.

Clean lines, held fast

Projects live in busy rooms: benches, bikes, fixtures that see real use. A low-profile head keeps surfaces smooth to the touch and easy to wipe down. Consistent sizing—M5 thread, 40mm length, 10mm head diameter—means predictable fit across thoughtful assemblies. Strength you can feel, elegance you don’t have to announce.

For the detail keeper

Builders and tinkerers who favor precise, low-profile fasteners with enduring finishes.
