HOLO-KROME
Since its founding in 1929, HOLO-KROME has been at the forefront of fastener development and innovation. HOLO-KROME began around a revolutionary idea to produce hex socket screws - by forming the metal into a pattern rather than machining it. To expand on our patents, we later invented the "cold forging" process, where the metal is preheated to improve its plasticity as it is formed. HOLO-KROMEs cold forging technology produces hexagon socket screws that provide greater strength and withstand higher fatigue strength. Our products are generally considered to be more precise and uniform. HOLO-KROMEs products have almost no cracks or fissures. These conditions are very common in some iron products. There is hardly an industry that can be considered as not needing HOLO-KROME products. In tool and machine manufacturing and processing of a wide variety of goods used in daily life; in the broad fields of transportation, agriculture, mining and construction, you will find countless places at work where HOLO-KROME products are ready to perform their important tasks - firmly resisting every moving force.
