Overview

The Minerallac Company SKU 38988 is a T-15H Star Tamperproof Insert Bit specifically designed for secure fastening with tamper-resistant Torx® screws. This single-ended bit features a T-15H tip with a central pin, engineered to precisely engage security Torx® fasteners while preventing the use of standard Torx® bits. Constructed from hardened steel, the bit delivers exceptional durability and resistance to wear, making it ideal for high-torque applications where cam-out must be minimized and tool life extended. The overall length measures exactly 1 inch, with a 1/4 inch hexagonal shank that ensures compatibility with a wide range of power drivers, hand tools, and tool holders. The hardened steel construction guarantees long-lasting performance, even in repetitive assembly and maintenance tasks where tamper-evident fasteners are required. This bit is particularly well-suited for applications in electronics manufacturing, automotive assembly, industrial control systems, and other environments where security and tamper resistance are critical. The T-15H tip design effectively deters unauthorized access by preventing the use of conventional Torx® bits. For additional versatility, Minerallac offers related products such as the double-ended bits SKU 40017 (T10 & T15) and SKU 40018 (T20 & T25), as well as the T-30H single-ended bit (SKU 38996) with a 1/4 inch hex shank.
