Fastener Length & Protrusion Gages
Precision Axial Measurement Systems for Length, Grip, and Protrusion Verification
Universal Fastener Gages designs and manufactures advanced length and protrusion measurement systems for verifying fastener stick-out, installed height, grip length, and NAS compliance. Our digital and mechanical systems deliver repeatable, production-ready measurement solutions for aerospace, medical, and high-performance fastener applications.
Complete Axial Fastener Measurement Solutions
Proper fastener length and protrusion are critical for structural integrity, load distribution, and compliance with aerospace and military specifications. Our systems measure installed fastener height, thread protrusion beyond mating surfaces, and overall length accuracy.
Designed for both shop-floor inspection and final quality verification, these systems provide high repeatability and simplified operator use in demanding production environments.
