براغي كتف مقبس 1/4 بوصة × 3 1/2 بوصة | رأس مقبس | محرك مقبس | ستانلس ستيل 18/8 (25/عبوة)

The shoulder on these is machined perfectly smooth, so my axle spins without any wobble or binding. I’ve used them for a jig pivot and the fit in the bore is exactly what I needed. Solid little parts for the price.

Was looking for some longer pivot screws for a jig I'm building, and these 3 1/2" ones fit the bill perfectly. The hex socket drive made installation a breeze with my allen key, and the stainless steel feels solid.

The precision-ground shoulder on these screws is exactly what I needed for a smooth bearing surface on a small jig I built. They fit perfectly into my pre-drilled holes and the hex drive made installation effortless. Very pleased with the quality of the stainless steel.
