What Sherex Fastening Solutions does

Sherex Fastening Solutions is a privately held manufacturer of blind rivet nuts, wedge locking washers and nuts, clinch nuts, compression limiters, and specialty fasteners, headquartered in Tonawanda, NY. Founded in 2004 and operating today as a wholly-owned division of PennEngineering, the company runs seven global manufacturing sites — three in North America and others in Mexico, Poland, and the United Kingdom — and is described as the largest manufacturer of rivet nuts in North America. Its product portfolio spans proprietary brands including Optisert (a round body rivet nut with engineered knurled body and underhead wedge delivering a 44% spin-out performance improvement in internal testing), RIV-FLOAT floating thread rivet nuts, ATLAS MaxTite (DoD-approved MS/NAS style rivet nuts), and the TEC Series and Disc-Lock wedge locking lines. The company also sells a full installation tooling platform including automated systems (in partnership with MDS), hydro-pneumatic tools (FLEX-5, FLEX-18, RIV943), pneumatic tools (SSG series), hand tools, and a Process Monitoring Installation System that records force-displacement curves in real time.

The company serves automotive OEMs and Tier 1/2 suppliers as its primary segment, with additional exposure to aerospace and defense, heavy truck, construction and agricultural equipment, renewable energy and battery storage, electric vehicles, and general industrial applications. It holds IATF 16949 (valid through 2027-09-05) and ISO 9001:2015 certifications, supports customers through a direct enterprise field sales motion with embedded technical sales engineers, and operates an online portal (sherexportal.com) plus a multi-language website (seven languages) and a 3D CAD model distribution partnership with TraceParts. Revenue is generated through one-time sales of fasteners and tooling plus custom engineering services for application-specific parts, with quote-based B2B pricing and no disclosed recurring or subscription streams.

Adam Pratt serves as President. Recent strategic actions include the 2025 launch of Optisert Stainless (corrosion-resistant variant), the 2026 launch of High Strength Rivet Nuts rated to Class 10 / Grade 8, prior acquisition of the ATLAS rivet nut product lines, and the MDS automation partnership. No revenue, headcount trend, or funding data is publicly disclosed.
