Product Specification

T20 X 1" TAMPER-RESISTANT STAR / TORX® SECURITY INSERT BIT - 1/4" HEX - 10 PACK

Benchmark Abrasives T20 x 1" Tamper-Resistant Star / TORX® Security Insert Bits are professional-grade driver bits built for contractors, maintenance professionals, distributors, and technicians working with protected or tamper-resistant fasteners. Each bit is manufactured from heat-treated S2 shock-resistant tool steel hardened to HRc 60 for the strength, toughness, and wear resistance required in repeated fastening applications.

The T20 security star tip is CNC precision-ground for accurate dimensions and reliable engagement with compatible T20 tamper-resistant star and TORX® fasteners. A center hole in the bit clears the security pin located inside the matching screw recess, allowing proper seating where a standard solid star bit cannot engage. The standard 1/4" hex shank makes these compact 1" insert bits easy to use with compatible bit holders, screwdrivers, drills, and other properly equipped driving tools.

Applications & Performance

Designed for driving and removing compatible T20 tamper-resistant star and TORX® security screws used in protected components, equipment panels, fixtures, enclosures, electronics, appliances, machinery, and other applications where security fasteners help discourage unauthorized access.

The center-hole design allows the bit to seat over the security pin in a matching tamper-resistant screw recess. For best performance, match the T20 tip to the correct fastener and keep the bit square to the screw during operation. Proper engagement improves torque transfer and helps reduce slipping, fastener damage, and premature bit wear.

Safety Tips

• Always wear appropriate eye protection and other PPE required for the application.
• Match the T20 security tip to the correct tamper-resistant fastener before applying torque.
• Confirm the center hole seats properly over the security pin in the screw recess.
• Keep the bit aligned squarely with the fastener to reduce slipping and tip damage.
• Make sure the bit or bit holder is fully seated and securely retained before operating the tool.
• Use controlled speed and torque appropriate for the fastener and work material.
• Inspect bits before use and replace any that are cracked, excessively worn, rounded, or otherwise damaged.
• Follow all operating and safety instructions supplied with the power tool or hand tool.
