Value Collection KP61011 3/8 in Split Lock Washer 250 Pack

Product Description

The VALUE COLLECTION KP61011 is a Grade 2 spring steel split lock washer sized for 3/8 inch screws. The washer features a zinc-plated finish for corrosion resistance and delivers reliable tension against fastener loosening caused by vibration or dynamic loads. Inside diameter ranges from 0.382 to 0.393 inches, maximum outside diameter is 0.691 inches, and thickness is 0.115 inches. This package contains 250 washers. Electricians, plumbers, HVAC technicians, and general maintenance professionals commonly use split lock washers when assembling equipment panels, pipe hangers, brackets, and mechanical connections that require a secure, vibration-resistant fastener joint.

Split lock washers of this type are used across residential and light commercial applications wherever a standard hex bolt or machine screw requires additional resistance to loosening. Common install scenarios include electrical panel and junction box assembly, HVAC equipment mounting, pipe support bracketing, and general mechanical fabrication. The 3/8 inch screw size fits widely used fastener families in trade work. The 250-piece pack suits service vehicles, job-site kits, and shop stock replenishment.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface prior to torquing. Ensure the split ring is fully seated and not deformed before tightening. Follow applicable torque requirements for the fastener grade and application per relevant codes such as NEC for electrical assemblies. Do not reuse split lock washers that have been fully compressed flat, as spring tension will be compromised.
