Penn Engineering

What Penn Engineering does

PennEngineering, doing business as PEM®, is a US-incorporated, privately held fastener manufacturer founded in 1942 in Pennsylvania. The company designs and produces self-clinching fasteners — pressed into sheet metal to create permanent threaded attachment points without welding, heat treatment, or tapping — across product families including nuts, studs, standoffs, captive screws, specialty fasteners, and threaded inserts. Its portfolio also spans surface-mount (SMT), broaching, and adhesive attachment technologies, complemented by installation equipment (Haeger®, PEMSERTER®), magnetic-release fasteners (GHOST™), EV-focused busbar connectors (eConnect®), and the 2024-acquired Sherex/ATLAS blind rivet nut line.

The company operates a global manufacturing and distribution footprint spanning North America (Danboro HQ; San Jose office opened 2021), Europe (Galway, Ireland technical and manufacturing centre), and Asia-Pacific (Kunshan, China as Asia headquarters; offices in Taiwan, Singapore, Japan, Korea). Revenue is generated primarily through hardware sales of fastener products and installation equipment, supplemented by value-added engineering services under the PEMedge® program — application engineering, testing, teardown, and FASTENERCLASS training — provided at no additional cost. Customers are enterprise OEMs across automotive electronics, consumer electronics, datacom/telecom, electric vehicles, aerospace and defense, medical, and industrial markets, reached via authorized distributors (including a March 2024 Endries International North American partnership), direct field sales with dedicated application engineers, and regional e-commerce storefronts in Asia.

The company is independent of any parent and has not disclosed venture or private equity investment. Strategic activity in 2023-2026 includes the Sherex acquisition, CharIN membership (2023), the Endries distribution partnership, the San Jose expansion, and a concentrated cadence of product launches targeting EV power electronics, IP-rated sealing, and AI server/datacom applications. Pricing is not publicly disclosed and is conducted via quote-based specification selling.
