How Can You Prevent Unauthorized Tampering in Your Security Enclosures?

Our one-way slotted sex thread bolt with 20 serrations provides dual-layer security: the tamperproof one-way drive allows installation but prevents removal, while the serrated head design ensures superior grip and vibration resistance. Manufactured from corrosion-resistant 302HQ stainless steel with ISO-compliant inspection protocols, these security fasteners deliver reliable anti-theft protection for alarm systems, surveillance equipment, and access control devices. Contact us to customize security solutions that meet your exact specifications.

With 45 years of fastener manufacturing expertise, we maintain rigorous quality control throughout production with comprehensive inspection protocols complying with ISO working instructions. Every security bolt undergoes meticulous measurement using calipers, protrusion-height gages, micrometers, and 2.5D/2D projectors to verify critical dimensions including across-flat measurements, head height, major/minor diameters, thread angle, and pitch. Our facility offers multiple stainless steel material options including 302HQ, 304SS, 305SS, 316SS, 410SS, 420SS, and 430SS to meet diverse application requirements. Whether you need standard specifications or custom security fasteners per your drawings, we deliver salt spray tested, high-quality tamperproof solutions for OEM manufacturers worldwide.
