Shannon Precision Fastener

What Shannon Precision Fastener does

Shannon Precision Fastener, LLC is a privately held precision fastener manufacturer founded in 2004 and headquartered in Madison Heights, Michigan. The company produces externally threaded bolts and screws in sizes M6-M24 and lengths from 16-381mm, using carbon, alloy, and stainless steel materials in property classes 4.8-13.9. Its core manufacturing capability is built on multi-die progressive cold forming technology with individual control of critical characteristics, which the company states enables it to routinely hold half of traditional tolerances. Operations span cold forming, thread rolling, pointing, heat treatment, and high-speed inspection, with an in-house A2LA-accredited laboratory supporting fatigue, torque tension, ultrasonic, and hardness testing.

The company operates five Michigan facilities totaling more than 625,000 sq ft, including three manufacturing plants (Madison Heights, Auburn Hills, Holly Manufacturing opened March 2023) and two distribution centers (Madison Heights and Holly). Shannon is vertically integrated through its wholly-owned subsidiary Emerald Steel Processing (acquired 2012), which supplies coiled rod, coating, annealing, and wire drawing services, and is affiliated with Michigan Rod Products (specialty products) and L&M Machining (tooling). Products serve automotive OEM and Tier 1 suppliers, heavy truck manufacturers, and industrial manufacturers, with licensed Taptite and Mathread specialty fastener designs in the portfolio.

Revenue is generated through enterprise B2B sales of custom-manufactured fasteners on a quote-based pricing model. The go-to-motion relies on direct field sales supported by two Vice Presidents of Sales (Commercial and Engineering), a Request-for-Quote process, and customer engineering support. The company has no disclosed digital distribution channels or third-party resellers, distributing directly to customers through its own distribution network. Customer relationships are anchored by long-tenured automotive OEM qualifications: General Motors has named Shannon a Supplier of the Year for seven consecutive years (2016-2022), Ford has granted Q1 certification, and Fiat Chrysler recognized the company as a 2018 Supplier of the Year Finalist. IATF 16949 certification is held across all three manufacturing locations, with ISO 14001 and ISO/IEC 17025 accreditations further supporting automotive and laboratory credibility.
