Fasteners

Industrial fasteners are hardware devices engineered to mechanically join, secure, or affix two or more objects together in structural and machinery assemblies.

Threaded fasteners (such as screws and bolts) utilize helical grooves to create removable joints, while non-threaded fasteners (such as rivets and pins) create permanent or semi-permanent mechanical bonds.

304 and 316 stainless steel provide maximum corrosion resistance and structural integrity in harsh outdoor, marine, and chemical environments.

Measure the outer major diameter of the thread using a caliper, and count the threads per inch (Imperial) or measure the distance between adjacent thread peaks in millimeters (Metric).

Thread galling is pressure-induced friction welding between mating threads, which can be prevented by applying anti-seize lubricant and reducing tightening speed.

Bolt grades and property classes define the fastener's tensile strength, yield strength, and material hardness under mechanical load.

No, metric and imperial fasteners have incompatible thread pitches and diameters, and attempting to mate them will strip or jam the threads.

Self-locking fasteners utilize nylon insert collars, prevailing torque threads, or serrated flanges to lock the fastener in place under continuous dynamic shock.

A bolt passes through unthreaded clearance holes and secures with a nut, whereas a screw threads directly into a tapped mating hole or forms its own threads.

Choose fasteners based on required tensile and shear load capacities, joint material thickness, operating temperatures, drive style, and environmental corrosion risks.
