PIN HEX MACHINE SCREW
PIN HEX BUTTON HEAD MACHINE SCREW
📌 Overview
The Stainless Steel Pin Hex Button Head Machine Screw is a high-security fastening solution designed for applications requiring tamper resistance, clean aesthetics, and reliable mechanical strength.
The button head profile provides a low, rounded appearance, while the pin-in-hex (tamper-proof) drive prevents unauthorized removal using standard hex keys.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, these screws offer excellent corrosion resistance, durability, and long service life, making them suitable for industrial, electrical, automotive, public infrastructure, and marine applications.
