What Electronic Fasteners does
Electronic Fasteners, Inc. (EFI) is a stocking distributor of mechanical fasteners and related hardware, founded in 1960 and headquartered in Canton, Massachusetts. The company supplies nuts, bolts, screws, rivets, pins, and specialty hardware in inch and metric sizes across stainless steel, nylon, silicon bronze, brass, and aluminum, serving industrial manufacturing, military/aerospace, MRO, stadium/venue, and electronics/telecommunications end markets. Distribution rights cover premium brands including Bossard, SPS/UNBRAKO, Holo-Krome, ITW Shakeproof, Southco, Spirol, 3M, Permatex, ND Industries, and Vibra-Tite. The company is dual-certified to ISO 9001:2015 and AS9120:2016 and holds ITAR registration, DFARS compliance, RoHS, REACH, TSCA, Conflict Minerals, and Proposition 65 compliance—credentials required to sell into aerospace and defense primes.
Revenue is generated primarily through one-time product sales supplemented by a meaningful managed-services layer. The Vendor Managed Inventory (VMI) and Fastener Management Program (FMP), in which EFI personnel visit customer facilities on a recurring basis to scan and replenish inventory, accounts for over half of total sales. The U-SCAN self-service variant lets customers upload their own orders for next-day shipment. Value-added services include kitting/bagging with customer part numbers, custom labeling, made-to-print custom manufacturing, passivation and plating finishing, and global sourcing. Distribution is sales-led and domestic, executed through a 1-888-890-7780 phone-based consultative sales operation, website quote-request forms, and on-site customer seminars. In 2024, Electronic Fasteners was acquired by OneMonroe (Monroe Engineering, LLC), which extended the company's vendor network and product surface while EFI continues to operate under its own brand.
