STI KIT-81 Tamper-Resistant Stainless Steel Screws
Overview
The KIT-81 is a fastener kit of tamper-resistant stainless steel screws designed for electronic lock and strike assemblies in access control deployments. Stainless steel construction resists corrosion in both indoor and outdoor environments, while the tamper-resistant design prevents unauthorized removal without specialized tools — a critical requirement when hardware integrity directly affects physical security. Use this kit to secure door strike and lock mechanisms operating at 9VDC in commercial and institutional access control systems.
Compatibility
The KIT-81 screws are sized and designed for electronic lock and strike hardware in standard access control installations. Compatible with 9VDC-operated strike and lock assemblies used in door control systems. If you are retrofitting or replacing fasteners on existing strike or lock hardware, verify hole sizing against your current installation before ordering — screw diameter and thread pitch must match existing hardware mounting points.
Installation Notes
Secure the frame or mounting plate using the tamper-resistant screws provided in the kit. Drill using a 7mm masonry drill bit for wall-mounted installations, then install the screws with appropriate hand tools or powered drivers — do not over-torque, as stainless steel fasteners can seize if excessive force is applied. For surface-mounted applications, ensure gaskets or washers are positioned to prevent water intrusion around the screw heads, particularly in outdoor or wet environments.
