Value Collection FWSIS037-100BX Sae Flat Washer 3/8 in Steel

Product Description

The VALUE COLLECTION FWSIS037-100BX is a standard SAE flat washer designed for use with 3/8 inch fasteners. Manufactured from steel with a plain finish, this washer distributes load across the bearing surface to protect the mating material and reduce loosening under vibration. It measures 13/32 inches inner diameter, 13/16 inches outer diameter, and 1/16 inch thick. Sold in a minimum order quantity of 100 pieces, this washer is appropriate for general mechanical assembly, structural fastening, and equipment maintenance across trade applications.

SAE flat washers in this size are commonly used in HVAC equipment assembly, electrical panel mounting, plumbing fixture installation, and general mechanical maintenance. The SAE standard profile provides a narrower outer diameter compared to USS washers, making it suitable for applications where washer footprint must stay close to the fastener head. These are frequently installed by HVAC technicians, plumbers, electricians, and general mechanical contractors during equipment installation or field repair work.

Installation Notes

Installation does not require specialized tools beyond standard hand or power wrenches. Ensure the fastener and mating surface are clean and free of debris before seating the washer. Apply consistent torque to the fastener per the equipment manufacturer's specifications. For outdoor or high-moisture applications, consider a coated or stainless alternative, as this plain finish steel washer is intended for dry or protected indoor environments.
