Value Collection 67582841 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION 67582841 is a 316 stainless steel split lock washer sized for 1/2 inch screws. The spring lock design applies axial tension under the fastener head, resisting loosening from vibration and torque relaxation. Manufactured to inch-system dimensions, this washer meets ASME, ANSI, BS, DIN, JIS, and NFE standards. The inside diameter ranges from 0.502 to 0.512 inches, the outside diameter ranges from 0.056 to 0.869 inches, and the thickness is 0.125 inches. The 316 stainless steel alloy provides corrosion resistance suitable for wet, chemical, or marine-adjacent environments. Plumbers, HVAC technicians, and electricians use split lock washers on equipment panels, piping hangers, and mechanical connections where vibration or thermal cycling could work fasteners loose.

This washer is suited for use in residential and light commercial mechanical applications where a 1/2 inch fastener is required and vibration-resistant locking is needed. Typical install scenarios include pipe hanger assemblies, equipment mounting brackets, electrical enclosure hardware, and HVAC unit structural connections. The 316 alloy grade makes it a practical choice in outdoor, poolside, or corrosive-atmosphere installations where standard 304 stainless or carbon steel would be inadequate.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Spring lock washer design resists fastener loosening under vibration and thermal cycling
• Sized for 1/2 inch screws with an inside diameter range of 0.502 to 0.512 inches
• Thickness of 0.125 inches provides consistent axial spring load
• Meets ASME, ANSI, BS, DIN, JIS, and NFE standards
• Inch-system dimensions for direct use with standard fractional fasteners

Compatibility

Designed as a standard split lock washer for 1/2 inch screw applications requiring 316 stainless steel construction and compliance with ASME, ANSI, BS, DIN, JIS, and NFE dimensional standards.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before torquing the fastener. Power down or isolate any equipment before accessing fastener points on energized panels or mechanical assemblies. Use appropriate hand tools and follow torque guidance from the equipment manufacturer or applicable code. Verify the washer is fully seated and not deformed after installation, as a damaged lock washer will not provide reliable axial tension.
