Value Collection 99729 Grade 8 Split Lock Washer 1 in

Product Description

The VALUE COLLECTION 99729 is a Grade 8 steel split lock washer sized for 1-inch screws and bolts. Split lock washers provide resistance against loosening caused by vibration and torque by biting into the mating surfaces when the fastener is tightened. This uncoated washer is manufactured to inch-system dimensions and is suited for high-strength bolted assemblies in mechanical, structural, and industrial applications. The Grade 8 material designation indicates a high-strength steel suitable for demanding fastening conditions. At 0.25 inches thick with a tightly controlled bore range, this washer seats consistently and delivers reliable clamping performance in properly torqued joints.

This split lock washer is used in bolted connections requiring a 1-inch screw or bolt. Typical applications include structural steel assemblies, heavy equipment fabrication, machinery mounting, and general mechanical maintenance where vibration-resistant fastening is required. It is installed by trades and technicians working in HVAC equipment mounting, electrical panel and equipment anchoring, plumbing equipment support, and general industrial assembly. Sold individually with a minimum order quantity of 10 pieces.

Installation Notes

Install this washer between the fastener head or nut and the mating surface before tightening. Ensure the bolt and nut grade are compatible with Grade 8 hardware to maintain joint integrity. Do not reuse split lock washers that have been fully compressed flat, as spring action will be lost. Follow applicable mechanical and structural codes for fastener torque and joint design requirements.
