Customer Reviews (4.6 / 5 · 5 reviews)

Elizabeth ★★★★★

Needed some long, strong M5 bolts for a custom tooling fixture, and the 100mm length with 12.9 hardness handled the load perfectly. The black oxide finish gives them a nice, uniform look that resists minor scuffs during assembly. Very precise threads too, no binding issues at all.

Ryan E. ★★★★★

Had to get longer bolts for a tooling project and these 100mm lengths fit the bill perfectly—the black oxide finish looks clean and seems durable. The hex drive seated firmly without stripping, which I always worry about with smaller sizes.

George ★★★★★

Used these on a jig for a machining fixture and the 12.9 alloy steel threads cut clean without any chips breaking off. The black oxide finish also held up well against the shop coolant, no rust after a week of use.
