Value Collection 36736 Split Lock Washer 1-1/4 in 25 Pack

Product Description

The VALUE COLLECTION 36736 is a split lock washer sized for 1-1/4 inch screws, manufactured from AISI 4037 alloy steel with a yellow zinc dichromate finish. Split lock washers create a spring-loaded bite between the fastener and mating surface, resisting loosening caused by vibration and torque relaxation. The inside diameter ranges from 1.254 to 1.28 inches, the maximum outside diameter is 2.036 inches, and the washer is 0.312 inches thick. This part is sold in a package of 25. It is installed by maintenance technicians, pipefitters, millwrights, and general tradespeople wherever reliable fastener retention is required.

This split lock washer is suited for industrial, mechanical, and structural assembly applications where alloy steel strength and corrosion-resistant finish are needed. The yellow zinc dichromate coating provides baseline protection against oxidation in moderate-exposure environments. Typical uses include securing bolted connections on mechanical equipment, framing assemblies, pipe supports, and HVAC equipment mounting. The AISI 4037 alloy steel grade offers higher tensile strength than plain low-carbon steel, making it appropriate for higher-load fastener joints.

Key Features

• AISI 4037 alloy steel construction for elevated tensile strength over standard carbon steel
• Yellow zinc dichromate finish for corrosion resistance in moderate-exposure environments
• Inside diameter range of 1.254 to 1.28 inches fits standard 1-1/4 inch fasteners
• 0.312 inches thick for consistent spring action and reliable locking bite
• Maximum outside diameter of 2.036 inches provides adequate bearing surface
• Sold in a package of 25 for job-site and shop inventory use

Compatibility

Designed as a standard split lock washer for use with 1-1/4 inch screws and bolts in inch-measurement fastener assemblies requiring an alloy steel washer with yellow zinc dichromate finish.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Position the washer with the split gap oriented so the edges can bite into both surfaces as the fastener is tightened. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking action. Follow applicable mechanical and structural codes for fastener torque requirements specific to the joint being assembled.
