Bolt & Fastener Testing Machines
Universal testing machines with dedicated bolt testing kits for tensile, proof load, wedge and shear testing per ISO 898-1 and ASTM F606.
Complete Fastener Testing Solutions
From M10 to M30 — tensile, proof load, wedge and shear testing of bolts, screws and threaded fasteners.
The Cermac Universal Fastener Testing Kit has been developed for accurate and reliable testing of bolts, screws, nuts and threaded fasteners in accordance with ISO 898-1, ISO 3506-1, ISO 15048-2 and ASTM F606.
The kit includes two load-bearing heads with extension rods, through-bushings and threaded inserts for bolt diameters from M10 to M30. Inclined washers (4°, 6°, 10°) for wedge tensile testing, shear test plates and nut proof load mandrels with hardness 45–50 HRC complete the system.
The kit installs on any Cermac UTM-E or UTM-H machine, providing a turnkey fastener testing solution with automatic reporting.
