Value Collection SEW8X0800-100BX M8 Lock Washer Ss 100pk

Product Description

The VALUE COLLECTION SEW8X0800-100BX is a stainless steel external tooth lock washer designed for use with M8 fasteners. It features an 8.4mm inside diameter and a 15.0mm outside diameter, with a thickness of 0.8mm. Constructed from Grade 18-8 Austenitic A2 stainless steel, this washer offers strong corrosion resistance for demanding environments. The serrated external teeth bite into the mating surface and fastener head to resist loosening caused by vibration or dynamic loads. Sold in a box of 100 pieces, it is a practical choice for maintenance, repair, and assembly work across plumbing, electrical, HVAC, and general mechanical applications.

This external tooth lock washer is suited for residential and commercial installations where M8 threaded fasteners require positive locking. Common applications include equipment mounting, panel assembly, pipe bracket fastening, and structural hardware connections. The 18-8 stainless steel construction makes it appropriate for wet, humid, or mildly corrosive environments where carbon steel hardware would be at risk. Installers working on outdoor equipment, pool mechanical rooms, or coastal-environment installations often specify stainless hardware for long-term reliability without galvanic compatibility concerns common to plated steel.

Installation Notes

Install this lock washer between the fastener head and the mating surface before torquing the fastener. Ensure the external teeth face the fastener head or the surface intended to grip, depending on assembly requirements. De-energize or depressurize any system before accessing fastened components during service. A2 stainless steel is not rated for all high-temperature applications, so verify suitability against system operating conditions before installation.
