Raised Countersunk A2 Stainless Steel Pin Hex Machine Screw

Engineered with an integrated pin mechanism within the hexagon socket, these A2 stainless steel machine screws deliver enhanced security against unauthorised removal. The pin-hex drive system demands a precisely matched driver, making these fasteners ideal for applications requiring tamper resistance and medium torque capacity. Manufactured to exacting standards, they resist corrosion whilst maintaining structural integrity in demanding environments. Available across our comprehensive range of metric and self-tapping variants, all finished in durable A2 stainless steel. Complementary pin-hex fasteners including socket cap screws, grub screws, and barrel nuts are also in stock.
