FORGED TO BE TOUGH
IN-HOUSE MANUFACTURING
Copper State can support your critical care or specialty product needs, for capital projects, shutdown and preventive maintenance campaigns, and aftermarket and service operations. In addition to manufacturing large diameter specialty product in-house, we source products through trusted supply chain partners around the world. We understand that our products may be critical to your operation, and our in-house operations ensure quality, accuracy, and on-time delivery.
PRODUCTS
We provide hot-forged bolts in size ranges from 1⁄2” to 4” (M16-M100). Materials include low and medium carbon steels, alloy steels and stainless and exotic metals to meet your specifications.
THREAD ROLLING
Need roll threaded products, including roll thread after heat treatment? We can help. Our roll threading process ensures more fatigue resistant fasteners, which are critical to some applications and equipment. In addition to cut threading, we run several roll threaders to complete our entire range of product diameters.
FORGING AND HEAT TREATING
We provide in-house forging up to 4” diameter with quench and temper heat treating. Each piece is subject to atmosphere-oil hardening and solution treating followed by age hardening. With state-of-the-art furnace controls and a full lab to provide metallurgical verifications, we can craft high quality bolts that fit every need.
LOAD MONITORING FASTENERS
Our Load Monitoring Fasteners are wireless, accurate, and automatic load monitoring bolts. These advanced bolts continuously track their true tension and alert you when they’re loose, helping you plan for repairs and prevent disasters.
