PERIGEE MANUFACTURING CO., INC. is a domestic manufacturer of screw-machined and CNC-machined fasteners and products, primarily hexagon, square, and round nuts. In addition to specialty fasteners, we manufacture precision turned products -- including bushings, fittings, pins, spacers and other products -- to print or specification.

Our precision manufacturing processes coupled with stringent statistical process controls (SPC) are cost effective for most production volumes, precise enough for close tolerance fasteners, and allow us to satisfy the most demanding product and quality requirements.

Perigee History

We specialize in slotted and castellated hexagon nuts; providing slotted nuts manufactured complete and slot milling for customer supplied nuts in volumes up to 1,000,000 pieces, as well as prototype machining capabilities for custom and special requirements. Our manufacturing capabilities range from ¼” to 3 ⅛” hexagon (1/4” to 3-1/2” round) and thread diameter #4 (.122”) through 2” / M3 through M50 in nearly all material grades and property classes. With our full on-site inspection lab, PPAP and First Article Inspection capabilities, government, safety & regulatory compliance, and automatic packaging lines with barcoding and RFID, Perigee meets and exceeds our customers’ demanding product and quality requirements.
