Fastener Force Washer

FT4000 Series Force Washer Transducers are ideal for use in threaded fastener torque-angle-tension testing!

Measure and record tension characteristics of threaded fasteners · Verify threaded fastener tension calculations · Test actual fasteners in a laboratory or assembly environment. The Model 4000 Force Washer Transducers are miniature load cells designed specifically for measuring fastener clamping forces. The design provides high stiffness in a small package, making these load cells ideal for static and dynamic measurements on fasteners, tie rods, or similar structural test applications where space limitations exist. Force washer transducers come in a variety of English and metric sizes. Options include cable connectors.
