About Micron Precision Screws
Micron Precision Screws Pvt. Ltd. (MPS Fasteners) was founded in 1979 by Romesh Vig and manufactures high-strength industrial fasteners in metric and inch sizes from M4 to M48 with lengths up to 400 mm, as well as custom fasteners made to customer drawings or samples. The portfolio includes hex bolts and socket head cap screws, studs, nuts, washers and hydraulic fittings (straight adaptors, ferrules, elbows, T-adaptors, banjo) up to A/F 80 mm. Production is carried out by cold forging, hot forging (lengths up to 550 mm), CNC turning, thread rolling (M5–M42), centerless grinding and band sawing, complemented by in-house heat treatment, zinc plating, Zn-Ni coating and Nano, Geomat and Dacromat coating. The material used is steel in strength classes 4.6 to 14.9. The group operates four manufacturing units in Rohtak and Faridabad (Haryana, India) as well as warehouses and branch offices in Germany (PRK Technologies GmbH), North America, South Africa, Australia and the UK (BMI Engineering Ltd). Customers include OEMs such as Caterpillar, JCB, Liebherr, Cummins, Ford, Bosch and Würth; around 30 % of production is exported.
