The L H Dottie Co FWBR38 is a 3/8-inch brass flat washer sold individually as a hardware accessory. Flat washers distribute load across a fastener bearing surface, reducing the risk of damage to the material being fastened and improving holding strength. Brass construction offers natural corrosion resistance, making this washer suitable for applications where ferrous hardware may corrode or where galvanic compatibility with brass or copper fasteners is a priority. Electricians, plumbers, and HVAC technicians commonly use brass flat washers in panel work, pipe connections, and equipment mounting where non-sparking or non-ferrous hardware is specified.
This washer is appropriate for residential and light commercial installations requiring a 3/8-inch fastener. Typical applications include electrical enclosure assembly, plumbing fixture mounting, HVAC equipment attachment, and general trade hardware work where corrosion resistance or brass compatibility is needed. It is sold as a single unit, making it easy to source exact quantities for service calls and repair jobs without overbuying bulk packs.
Designed as a standard flat washer for use with 3/8-inch bolts, screws, and threaded rod in trade hardware applications requiring brass construction.
Install using standard hand tools appropriate for the fastener type. Ensure the washer seats flat against the mating surface before applying torque. De-energize electrical systems and shut off fluid supply lines before working in proximity to live circuits or pressurized plumbing. Follow applicable NEC, IPC, or local code requirements for hardware specifications in regulated installations.
