PIN HEX SELF TAPPPING
PIN HEX BUTTON HEAD SELF TAPPING SCREW
📌 Overview
The Stainless Steel Pin Hex Button Head Self Tapping Screw is a high-security fastening solution designed for applications requiring tamper resistance, clean aesthetics, and reliable self-tapping performance.
It features a button head with a pin hex (tamper-proof hex socket) drive, preventing unauthorized removal while allowing controlled installation using a special pin-hex key.
The self-tapping thread eliminates the need for pre-tapped holes, enabling the screw to cut its own threads into metal, plastic, or soft alloys. Manufactured from SS304 (A2) and SS316 (A4) stainless steel, these screws provide excellent corrosion resistance, strength, and durability, making them suitable for indoor, outdoor, and marine environments.
