Fasteners | ASTM A193 | A194 | A320
PM Industries manufactures, supplies, and stocks industrial fasteners, the hardware that joins and secures two or more components into one structural assembly. Fasteners hold modern engineering together, and they come in many forms, including bolts, screws, nuts, washers, studs, rivets, and pins, each matched to a load, a vibration level, or an environment. The job of a good fastener is a reliable joint that takes tensile, shear, and cyclic fatigue stress without loosening or pulling apart. Some are made for a permanent joint, such as heavy-duty rivets, while threaded types allow repeated assembly and disassembly for routine maintenance.
Material and surface treatment are chosen for the conditions the fastener will face. Common base metals include high-tensile carbon steel, austenitic and martensitic stainless steel, alloy steel, and non-ferrous metals such as titanium, brass, and aluminum. For hard service with aggressive chemicals or constant moisture, fasteners get protective coatings such as hot-dip galvanizing, zinc plating, cadmium plating, or fluoropolymer finishes to resist corrosion and stress-corrosion cracking. Precise thread geometry, paired with locking features such as nylon inserts, serrated flanges, or split washers, keeps clamping force from dropping off under vibration and changing temperature.
Because they hold structures safely and stop dangerous component failures, fasteners are used across every major industry. Aerospace and automotive work uses lightweight, high-strength fasteners to secure engine parts, fuselage panels, and chassis assemblies under heavy dynamic load. Construction, heavy machinery, and offshore energy rely on high-yield structural bolts and studs to keep bridges, tall buildings, pressure vessels, and subsea manifolds sound. PM Industries supplies them across a range of dimensional standards, thread pitches, and strength grades, so each fastener can be matched to the joint and the load.
As a manufacturer, supplier, and stockist of industrial fasteners, PM Industries ships standard and custom fasteners against fast quotes.

Frequently Asked Questions
A common first question is which material to choose. Carbon steel suits general structural work, stainless steel adds corrosion resistance, alloy steel gives high strength, and non-ferrous metals such as titanium, brass, and aluminum fit weight or chemical needs. PM Industries supplies all of these and can match the metal to the service.
Buyers also ask how to stop fasteners from loosening under vibration. Locking features such as nylon-insert nuts, serrated flange heads, and split washers, along with the correct thread fit and torque, keep the clamping force in place. PM Industries can advise on the right locking method for the application.
On coatings and grades, fasteners are offered with hot-dip galvanizing, zinc plating, and other finishes for corrosion protection, across a range of strength grades and thread pitches. Typical uses include aerospace, automotive, construction, heavy machinery, and offshore energy work.
