#1184 6-Lobe (TX) GO / NO-GO Gage
Combined GO / NO-GO inspection for internal 6-Lobe recess head screws. Built for fast, repeatable verification of minimum acceptable form and maximum allowable recess condition in one compact production gage.
Ideal for fastener manufacturers, aerospace suppliers, medical device manufacturers, distributors, and quality teams inspecting internal 6-Lobe recess head screws.
One compact gage for lower and upper recess condition checks.
The #1184 6-Lobe (TX) GO / NO-GO Gage helps quality teams verify internal 6-Lobe recess head screws with a simple pass/fail inspection routine. The GO end verifies the recess meets the minimum acceptable condition for driver engagement. The NO-GO end confirms the recess does not exceed the maximum allowable condition.
Reduce Tool Changes
Combining GO and NO-GO verification in one tool helps operators move faster without switching between separate gages.
Improve Repeatability
A clear inspection routine supports consistent use on the production floor, in receiving inspection, and during final verification.
Built around the inspection points that matter most.
Use the #1184 when a customer print, quality plan, or production requirement calls for both minimum and maximum internal 6-Lobe recess condition verification.
GO Verification
Confirms the internal 6-Lobe recess meets the minimum acceptable condition for proper driver engagement.
NO-GO Verification
Confirms the recess does not exceed the maximum allowable condition for the inspection requirement.
Combined Inspection
Combines both inspection ends in one compact tool to reduce tool changes and simplify operator use.
Production Consistency
Supports repeatable inspection routines in manufacturing, receiving inspection, and quality control.
Documented Control
Long-form calibration certificate support helps quality teams maintain dimensional traceability.
Fastener Readiness
Helps verify recess condition before final assembly, shipment, or customer acceptance.
Simple pass/fail inspection for production teams.
The #1184 keeps the inspection process clear: choose the correct size, check the GO side, check the NO-GO side, and record results when documentation is required.
Verifies the recess meets the minimum acceptable condition for driver engagement.
Confirms the recess does not exceed the maximum allowable size condition.
