براغي رأس أسطوانية 1/4-20 × 3-1/2 بوصة | محرك سداسي | ستانلس ستيل 18/8 (100 / عبوة)

I needed some long stainless fasteners for a machine guard, and these 3-1/2" socket cap screws were exactly the right length. The hex drive seated perfectly without any cam-out, which I appreciate when working in tight spots. They look clean and corrosion-resistant so far.

Ordered these for a tooling fixture and the 18/8 stainless finish is holding up great—no rust spots after a week in a humid shop. The 3-1/2" length gave me just enough thread engagement for my jig, and the hex socket drive saved my knuckles versus a standard bolt.

The hex socket drive made these easy to torque down in tight spots on my tooling setup, and the 18/8 stainless finish hasn't shown any corrosion after a few weeks in a damp shop. They're exactly as described and a solid value for the quantity.
