Cylindrical Head Torx Screw With Pin

Cylindrical Head Torx Security Screws with Pin are designed for fastening applications where resistance to unauthorized removal is important. They feature a cylindrical head and a six-lobe Torx drive with a central security pin, which requires a compatible pin-in-Torx driver for installation and removal. Unlike standard Torx screws, the central pin prevents the use of ordinary Torx bits, providing an additional level of tamper resistance. The cylindrical head offers a compact, practical fastening design, making these security screws suitable for equipment housings, electrical enclosures, machinery, and other assemblies where access to fastened components needs to be restricted.

We supply cylindrical head Torx security screws with pin in different thread sizes, lengths, materials, and surface finishes to meet various industrial requirements. Our manufacturing capabilities include cold heading, thread rolling, and precision machining, supporting consistent dimensional accuracy and reliable thread quality. For applications with specific fastening requirements, we can also work from customer drawings or technical specifications to customize head dimensions, drive configurations, and security pin features. This flexibility allows us to supply security fasteners for both standard industrial applications and specialized assembly requirements.
