Product Specification

T-20 X 1" TAMPER PROOF STAR INSERT BIT 1/4" HEX - 10 PACK

Benchmark Abrasives T-20 X 1" Tamper Proof Star Insert Bit 1/4" hex are CNC machine ground out of heat-treated S2 Shock resistant tool steel, which will withstand extremely high torque output and provide maximum durability.  They feature a post in the center of the recess. The post in the insert bit will only fit into tamper-resistant TORX bits. They are used in a hex bit screwdriver or wrench to insert or remove star insert security screws.

Star Insert Bits for Tamper Resistant are engineered for maximum durability and long life with impact drivers. These star insert bits are designed with precision tip geometry so they fit fasteners more precisely, which reduces stripping. The precision geometry of these bit delivers superior fitment, and reduce cam-out. The hole in the center in each star insert bit causes it to be tamper-resistant. It can be used in automobiles, repairs, engines, motorcycles, interiors, dashboards, computers, cable boxes, toys, appliances, and consumer electronics.

Joshua N. ★★★★★

The CNC machining on these 1" tamper proof star bits gives a really snug fit in security screws; no wobble at all. My first pack lasted through dozens of projects before I needed a replacement.

Olivia S. ★★★★★

I’ve been using these bits for a couple weeks and they’ve held up well in a few tough screws. The 1" length is just right for getting into tight spots without needing an extension. Nice to have a 10-pack so I’m not scrambling to find one when the first strips out.

Lucy M. ★★★★★

These bits fit snugly and don't slip at all on the tamper-proof screws I need them for. Nice to have a ten-pack since I always seem to misplace one mid-project.
