Common Mechanical Fasteners

One of the most common types of Mechanical Fasteners is the #140 and #190 Plategrip fastener.

The Traditional Plategrip teeth overlap the edges of the plates and provide extra holding power on thin belts. Passing smoothly over conveyor pulleys, Plategrip fasteners allow natural troughing of belts and smooth operation on both sides, through trippers and scrapers, as well as over crowned or takeup pulleys.

All buckets of solid plate fasteners have pre-assembled bolts and bottom plates that utilize our patented system, which includes the use of a special thin metal washer to clinch the bolt to the bottom plate during installation of the belt fasteners. This has proven to be superior to the use of plastic or nylon washers, which can slide along the bolt threads.

We Can supply these plate fasteners in boxes of 25 or buckets of 100 count with all the tooling & templates
