Overview

The NSi Industries JSLW9D 3/8" split lock washer is a precision-engineered fastening solution manufactured in the USA from 18-8 stainless steel, meeting ASTM F844 and ASME B18.22.1 standards for dimensional accuracy and material properties. This lock washer features a split ring design that compresses when tightened, creating tension between the bolt head or nut and the mating surface to prevent loosening from vibration or torque. The 18-8 stainless steel composition provides excellent corrosion resistance in outdoor, marine, and industrial environments, maintaining integrity under exposure to moisture, chemicals, and temperature fluctuations ranging from -320°F to 1500°F (-196°C to 816°C). With a 3/8" nominal size (0.375" ±0.005"), it is compatible with standard 3/8" bolts and fasteners, including SAE Grade 5 and Grade 8 hardware. Ideal for machinery assembly, automotive applications, construction projects, and equipment mounting, this lock washer meets stringent quality standards for reliability and durability. NSi Industries ensures consistent sizing and material properties for dependable performance in critical fastening applications, with a Rockwell hardness of B80-B100 and a tensile strength of 80,000-100,000 PSI. The washer's split design allows for a 360° grip around the fastener, enhancing vibration resistance and maintaining joint integrity under dynamic loads.
