Product Overview
The #1181 6-Lobe (TX) GO Penetration Gage is built for production and receiving inspection of internal 6-Lobe recess head screws where reliable minimum form verification is essential. This gage helps confirm that the recess will properly accept the intended driver and meet the expected manufacturing requirement.
GO penetration gaging provides a fast, repeatable method for checking internal drive quality on incoming parts and on the production floor. It supports process control, helps identify undersized or irregular recess conditions, and gives quality teams greater confidence before assembly or shipment.
Universal Punch designs precision gaging systems for demanding manufacturing environments where repeatability, durability, and professional inspection performance are expected every day.
What This Gage Checks
- Minimum acceptable internal 6-Lobe recess form
- Driver compatibility and usable recess engagement
- Receiving inspection consistency
- Production process control across manufacturing lots
- Conformance prior to final assembly or shipment
