Value Collection R83920129 Split Lock Washer No. 6 18-8 Ss

Product Description

The VALUE COLLECTION R83920129 is a Number 6 screw split lock washer manufactured from 18-8 stainless steel. Split lock washers are designed to resist fastener loosening caused by vibration and thermal cycling by biting into the mating surface and underside of the fastener head. This washer measures 0.141 to 0.148 inches inside diameter, 0.25 to 0.266 inches outside diameter, and 0.031 inches thick. It is suited for use in plumbing, electrical, HVAC, and general mechanical assemblies where corrosion resistance and reliable clamping force are required. Licensed tradespeople and maintenance professionals install these washers in both interior and exterior applications.

This split lock washer is intended for use with Number 6 fasteners in inch-measurement systems. Its 18-8 stainless steel construction resists rust and oxidation, making it appropriate for wet environments, outdoor installations, and applications where dissimilar metals may cause galvanic concerns with standard steel hardware. It is sold individually and ordered in multiples of 500, making it suitable for contractors and service shops maintaining bulk fastener inventory.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Split lock design resists fastener loosening under vibration and thermal cycling
• Inside diameter range of 0.141 to 0.148 inches fits Number 6 screws
• Outside diameter range of 0.25 to 0.266 inches provides broad bearing surface coverage
• 0.031 inch thickness for standard light-duty locking applications
• Inch measurement system sizing for compatibility with standard US fastener sets

Compatibility

Designed for use with Number 6 screws in inch-measurement fastener assemblies. Suitable for general mechanical, electrical, plumbing, and HVAC applications requiring a corrosion-resistant split lock washer.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface, with the split gap oriented to allow the washer to bite upon final tightening. Do not reuse split lock washers once they have been fully compressed, as the locking action is reduced. Verify fastener size compatibility before installation. Follow applicable mechanical codes and torque guidelines specified for the fastener and joint being assembled.
