Value Collection 39736 Split Lock Washer 1-1/4 in Alloy Steel 10pk

Product Description

The VALUE COLLECTION 39736 is a split lock washer designed for use with 1-1/4 inch screw sizes. Manufactured from AISI 4037 alloy steel, it delivers reliable tension and vibration resistance under load. The zinc yellow dichromate finish provides corrosion protection suitable for general industrial and mechanical applications. With an inside diameter ranging from 1.254 to 1.28 inches, a maximum outside diameter of 2.036 inches, and a thickness of 0.312 inches, this washer meets standard inch-system dimensional requirements. Each package contains 10 washers.

Split lock washers are used in bolted assemblies where vibration or dynamic loading could cause fasteners to loosen over time. This washer is suitable for use in HVAC equipment mounting, electrical panel assembly, plumbing fixture installation, mechanical equipment frames, and general trade work wherever a 1-1/4 inch screw or bolt requires a locking element. The AISI 4037 alloy steel construction makes it appropriate for moderate-strength fastening applications in both residential and light commercial settings.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing down the fastener. Ensure the fastener and washer material are compatible to avoid galvanic corrosion in dissimilar-metal assemblies. Follow applicable mechanical codes and equipment manufacturer torque specifications when tightening. Inspect washers for deformation or cracking before installation and do not reuse washers that have been fully compressed flat.
