براغي كوب بوينت سوكيت سيت 5/8-18 × 4 بوصة | فولاذ سبائكي (25 / عبوة)

Used a full box of these holding a hefty cam in place and not a single one stripped or rounded out, the cup point bites into the shaft nicely. Alloy steel feels plenty tough for repeated adjustments. Shipping was quick so I'm already ordering another pack.

I needed set screws that could handle some serious torque without stripping, and the hex socket drive on these delivered perfectly when I tightened them in a tight machine adjustment. The cup point bit firmly into the shaft with no slippage at all, even under pressure. Just what I hoped for.

Threaded these into a heavy-duty bracket and the cup point bit into the shaft perfectly for a solid hold. The alloy steel feels tough, and the hex drive allowed me to torque them down easily in a tight spot. Exactly what I needed for that application.
