Value Collection MP30723 Split Lock Washer 316 Ss 50pk

Product Description

The VALUE COLLECTION MP30723 is a 1/2 inch split lock washer made from 316 stainless steel, sold in a pack of 50. Split lock washers create tension under a fastener head or nut to resist loosening caused by vibration and torque relaxation. The 316 stainless steel alloy provides strong resistance to corrosion, including chloride and salt environments, making this washer suitable for demanding service conditions. With an inside diameter ranging from 0.506 to 0.518 inches, an outside diameter of 0.873 to 0.883 inches, and a thickness of 0.125 inches, these washers are dimensionally consistent for high-volume assembly work. Plumbers, electricians, HVAC techs, and mechanical contractors reach for these when fastener retention and corrosion resistance are both required.

These split lock washers are used in residential and commercial applications where standard carbon steel hardware would corrode or where regulatory standards call for stainless fastener hardware. Common install scenarios include pipe hangers, equipment mounting brackets, panel enclosures, pool and spa equipment, outdoor condensing units, and marine-adjacent environments. The 50-piece pack suits service vans and shop inventory without overstocking.

Key Features

• 316 stainless steel construction for strong chloride and corrosion resistance
• Split lock design creates spring tension to resist vibration-induced loosening
• Inside diameter 0.506 to 0.518 inches fits standard 1/2 inch fastener shanks
• Outside diameter 0.873 to 0.883 inches for broad bearing surface under nut or bolt head
• Thickness of 0.125 inches provides consistent deflection and locking force
• Pack of 50 sized for field service and bench stock replenishment

Compatibility

Designed for use with 1/2 inch screw and bolt fasteners in inch-measurement assemblies requiring a split lock washer. Suitable wherever 316 stainless steel hardware is specified.

Installation Notes

Install this washer between the fastener head or nut and the mating surface with the split gap oriented to bite into both surfaces as the fastener is tightened. Ensure the fastener and mating hardware are also stainless or a compatible alloy to avoid galvanic corrosion. Follow applicable torque guidelines for the fastener size and joint material. Do not reuse split lock washers that have been fully compressed flat, as locking effectiveness is reduced.
