Up To 20X Faster than Hand Tapping
Spiral-point tap, made for impact wrenches. By Unibor. Built For Metal.™
The Power Tool Industry Association 2025 Tool Innovation Award recognises tools that meaningfully change how tradespeople work.
SITEH3RO™ won for letting one operator do work that previously needed a drill press and bench setup, using the impact wrench they already own.
Most taps shatter under impact-wrench torque. SITEH3RO™ taps are specifically engineered for impact-wrench drive. No drill press required, no bench vise. Thread steel on the job, in place.
Fits any 1/2" or 3/4" square-drive impact wrench.
SITEH3RO™ is the direct-to-tradesperson line from Unibor, a Lombard, Illinois metalworking-tool specialist that has supplied bridge builders, structural fabricators, and US shipyards for decades.
Designed by engineers who've spent careers in fab shops, to the standards real tradespeople set.
