ISO Hexalobular Handheld Inspection Gages
Penetration, GO / NO-GO, fallaway, and final inspection gages for ISO-compliant hexalobular drive systems.
Universal Fastener Gages manufactures ISO hexalobular handheld inspection gages engineered for precise recess verification and dimensional compliance. Designed to support ISO fastener standards and global manufacturing requirements, our handheld systems provide repeatable, objective inspection without the need for bench-mounted equipment.
What Is ISO Hexalobular?
ISO hexalobular drive systems are defined by international standards and are commonly specified in global fastener manufacturing programs. These systems are engineered for consistent torque transmission and dimensional control.
ISO hexalobular handheld gages are used to verify recess penetration depth, GO dimensional compliance, NO-GO rejection limits, fallaway characteristics, and final inspection conformance.
These inspection tools support compliance with international quality standards and customer-specific requirements.

Inspection Types Explained
Penetration – Verifies recess depth supports proper functional driver engagement.
GO Inspection – Confirms minimum acceptable geometry for torque transmission.
NO-GO Inspection – Detects dimensional nonconformance beyond allowable tolerance.
Fallaway – Ensures proper disengagement behavior in applicable systems.
Final Inspection – Used for documented compliance verification prior to shipment.
