Value Collection R52000345 No 10 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION R52000345 is a No. 10 split lock washer manufactured from 316 stainless steel with a bright, uncoated finish. Split lock washers apply spring tension when fastened, resisting loosening caused by vibration and thermal cycling. This washer measures 0.193 to 0.200 inches inside diameter, 0.334 inches outside diameter, and 0.047 inches thick. At 35 to 43 HRC hardness, it delivers reliable bite and holding force in demanding environments. Licensed tradespeople and maintenance professionals install these washers in plumbing, HVAC, electrical enclosure, and general mechanical assemblies where corrosion resistance is required.

This washer is suited for indoor and outdoor applications where exposure to moisture, chemicals, or salt air makes 316 stainless steel the preferred material choice over standard 18-8 grades. Typical use cases include marine hardware, food-service equipment, pool and spa mechanical assemblies, and corrosive-environment fastener joints. The uncoated bright finish requires no additional surface preparation prior to installation.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chemical-exposure environments
• 0.047 inches thickness with 35 to 43 HRC hardness for consistent spring tension and locking action
• Inside diameter range of 0.193 to 0.200 inches fits No. 10 screw shafts
• Bright uncoated finish — no coating delamination risk over time
• Meets ASME B18.21.1 and SAE J405 fastener standards

Compatibility

Designed for use with No. 10 screws and bolts in standard inch-measurement fastener assemblies per ASME B18.21.1.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before torquing. Power down or de-energize any equipment before accessing fastener points in electrical or HVAC assemblies. Do not reuse split lock washers that have been fully compressed flat, as they will not provide effective locking force after set. A standard wrench or screwdriver appropriate to the fastener drive type is all that is required for installation.
