Value Collection 87925186 Split Lock Washer 3/8 in 18-8 Ss

Product Description

The VALUE COLLECTION 87925186 is an 18-8 stainless steel split lock washer sized for 3/8 inch screws. The spring lock design applies tension against the fastener to resist loosening caused by vibration, torque relaxation, or thermal cycling. The washer measures 0.377 to 0.385 inches inside diameter, 0.156 to 0.680 inches outside diameter, and 0.094 inches thick. Manufactured to ASME, ANSI, BS, DIN, JIS, and NFE standards, this washer suits general mechanical assembly work across plumbing, HVAC, electrical, and structural applications where stainless corrosion resistance is required.

This split lock washer is used in residential and commercial installations wherever a 3/8 inch fastener must be secured against loosening. Typical applications include pipe hanger assemblies, equipment mounting brackets, electrical enclosure hardware, and HVAC unit fastening. The 18-8 stainless steel construction makes it suitable for humid, wet, or mildly corrosive environments such as mechanical rooms, rooftop equipment, and outdoor electrical panels. It is installed by HVAC technicians, plumbers, electricians, and general mechanical contractors as part of standard fastener assemblies.

Key Features

• Spring lock design resists fastener loosening under vibration and thermal cycling
• 18-8 stainless steel construction provides corrosion resistance in wet and humid environments
• Meets ASME, ANSI, BS, DIN, JIS, and NFE standards
• Inside diameter range of 0.377 to 0.385 inches fits standard 3/8 inch screws and bolts
• 0.094 inch thickness delivers consistent spring tension across typical clamping loads

Compatibility

Designed for use with 3/8 inch screws and bolts in standard inch-measurement fastener assemblies across mechanical, plumbing, electrical, and HVAC applications.

Installation Notes

Install with the split ends contacting the bearing surface so the washer can apply outward spring tension as the fastener is torqued. Power down or de-energize any equipment before accessing fastener assemblies on electrical or HVAC components. Use hand tools or a calibrated torque wrench appropriate to the fastener grade and base material. Follow applicable code requirements under NEC, IFGC, or IPC as relevant to the assembly being serviced.
