براغي رأس مقبس 5/16-24 × 3/4 بوصة | محرك سداسي | فولاذ سبيكة (300/عبوة)

I needed a bulk pack for building jigs, and the hex socket drive on these makes them much easier to install in tight spaces. The alloy steel feels tough and durable, and 300 pieces is great value. Perfect for my precision assemblies.

The hex socket drive grips the allen key perfectly with zero wobble, which makes threading these into my jig fixtures a breeze. For the price, you're getting a solid box of alloy steel screws that feel tougher than the standard hardware store stuff.

Packed 300 to a box, these alloy steel screws have a clean hex socket that didn’t strip when I torqued them into a fixture. Only minor gripe is the packaging could be sturdier, but the screws themselves are consistent in thread and length.
