5/32" × 11/16" دبابيس زنبركية | مشقوقة | ستانلس ستيل 420 (500 / عبوة)

Used these to pin two alignment blocks on a jig that sees constant vibration, and they’ve held tight through a few hundred cycles now. The 420 stainless finish is clean and corrosion-free so far, and the slotted design made them easy to drive without any binding.

Installed a few dozen of these into a fixture that sees constant vibration, and they've held tight through every cycle so far. The 420 stainless finish is a solid upgrade over the plain steel pins I used to buy, especially where rust was a recurring problem. Slotted design made them easy to drive in

Was a bit skeptical about stainless spring pins at this price point, but these fit perfectly into my gauge plate and haven't budged under vibration during testing. The slotted heads made install simple with just a flathead.
