براغي مقبس كتف 5/16" × 4" | رأس مقبس | محرك مقبس | ستانلس ستيل 18/8 (25/عبوة)

Noticed these have a nice smooth finish on the shoulder that makes them work perfectly as a bearing surface in my small assembly jig. The socket drive grips well enough to sink them flush without stripping.

The precision-ground shoulder on these screws made setting up a jig for repetitive drilling much more accurate than I expected. They fit perfectly as pivot points on my custom fixture.

The precision-ground shoulder on these screws made aligning the pivot on my jig perfectly smooth. They're exactly the right length for a 4-inch axle setup. Fast shipping and solid packaging.
