Nuts and Washers

About

Nuts and Washers Nuts and washers are foundational components for any secure fastening system. Whether used in construction, transportation, or mechanical assemblies, they work together to create strong, stable joints capable of withstanding pressure, vibration, and load shifts. Washers are thin metal plates with a central hole, employed to evenly distribute the load of threaded fasteners like bolts or threaded rod. Their purpose is to avert loss of load due to tightening pressure, ensuring long-term stability and structural integrity. Washer Types Available USS Flat Washers: Also known as plain washers , these are versatile fasteners designed to evenly distribute load. Available in unfinished, hot dip galvanized, and stainless steel (18-8 and 316) varieties. Split Lock Washers: Featuring offset split ends, these split lock washers act like springs to resist loosening caused by vibration. Commonly used beneath nuts to maintain load retention. USS F436 Structural Flat Washers: F436 Flat Washers are built for use with A325 hex bolts, these washers increase bearing surface area and protect materials during installation in structural applications. SAE Flat Washers: SAE Flat washers are designed to pair with bolts and threaded rod of matching material. Available in 316 and 18-8 stainless steel, they evenly spread the load and reduce surface pressure. Direct Tension Indicator (DTI) Washers: DTI washers include slotted bumps to verify tension during bolt installation, ensuring accuracy without over-tightening. Offered in plain and mechanically galvanized finishes. DTI Squirter Washers: An advanced version of DTI washers with orange silicone that visibly indicates when proper tension has been achieved, adding a layer of assurance to critical connections. Nut Types Available Nuts feature threaded holes and are designed to join multiple components when used with bolts. Our inventory covers a wide variety of nut styles for general and structural applications. Coupling Nuts: Al
