#1281 Extra (TXP) GO Penetration Gage
Universal Punch Corp. | Precision Gaging
Precision GO penetration gaging for internal Extra (TXP) recess head screws. Designed for production and receiving inspection where minimum acceptable recess form, proper driver fit, and consistent drive geometry are essential to high-performance fastening systems.
Product Overview
The #1281 Extra (TXP) GO Penetration Gage is designed for production and receiving inspection of internal Extra (TXP) recess head screws where minimum acceptable recess form and proper driver engagement must be verified. It provides a repeatable inspection method for confirming that the recess remains within the intended usable condition for the enhanced drive system.
In practical use, GO penetration gaging helps quality teams verify that the recess will properly accept the mating driver while supporting consistent inspection across incoming parts, work cells, and production lots. It is especially valuable in high-performance fastening programs where fit, torque transfer, and tool life matter.
Universal Punch designed the Extra (TXP) family to deliver improved driver bit life, superior fit between drive tool and fastener, higher torque transfer capability, reduced camout, and reduced slippage compared with many older drive systems.
What This Gage Checks
- Minimum acceptable internal Extra (TXP) recess form
- Driver compatibility and usable recess engagement
- Receiving inspection consistency
- Production process control across manufacturing lots
- Drive quality before final assembly or shipment
