براغي رأس أسطواني 1/2-13 × 14 بوصة | تجويف سداسي | خيط جزئي | فولاذ سبائكي مؤكسد حراري أسود (2 / عبوة)

These came in the black oxide finish I needed for a tooling jig, and the hex drive makes them easy to torque down in tight spots. The partially threaded design helps with alignment in thick assemblies too.

Finally found a 14-inch cap screw that actually fits my jig setup without needing a custom order. The black oxide finish on these is a nice touch for resisting minor scuffs in the shop.

The hex socket drive fit my ratchet perfectly, making installation straightforward on a heavy jig I’m building. Only thing is the black oxide coating seemed a bit thin in a couple spots, but they’re still solid for the price.
