Sowant Precision Gage specializes in manufacturing high-precision UNJ thread plug and ring gauges, ensuring superior quality, short lead times, and competitive pricing. Our UNJ thread gauges are made from CR15 bearing steel, offering exceptional hardness and durability. Each gauge is precision-ground on CNC thread grinding machines, guaranteeing stable and reliable accuracy comparable to European and American standards.
In addition to UNJ thread gauges, we also produce:
ACME thread plug and ring gauges
HBPV back pressure valve thread gauges
BUTTRESS thread gauges
Furthermore, we are an authorized distributor of Gagemaker thread measuring instruments, including models such as PD-6001 and PD-8001.
