5/16-18 × 4-1/2" براغي رأس مقبس | رأس زر مقبس سداسي | كامل الخيط | ستانلس ستيل 18/8 (50/عبوة)

The hex socket drive seated perfectly on my driver without any wobble, and the 18/8 stainless finish feels solid for the jig I’m building. Threads ran clean through my steel plate, no binding or burrs. Exactly the consistency I needed across all 50 pieces.

These 4-1/2" screws are exactly what I needed for a custom jig I'm building. The hex socket drive made installation much easier than using a traditional slotted head. Very solid feel with the stainless steel material.

The full thread engagement on these 4.5-inch stainless screws is great for my heavy machinery jigs, and the hex drive bit grabs securely without stripping. They feel solid and corrosion-resistant right out of the package.
