Since its formation in 1929, Holo-Krome has been at the forefront of fastener development and innovation. The company was organized around what was a revolutionary idea at the time - the manufacture of socket screws by metal forming or heading rather than machining. Extending our heritage of innovation, we later invented the “Thermo-Forged®” process in which the metal is prewarmed to improve its plasticity for forming. Holo-Krome’s Thermo-Forging techniques result in socket screws which are more precise, offer greater strength and afford higher fatigue resistance. Our products are recognized for their uniformity, and for being virtually free of the bursts, minute cracks, tears and fractures sometimes found in other, inferior, products.
