Trapezoidal threaded nuts - bronze, round
We supply trapezoidal threaded nuts made of bronze (CuSn7ZnPb) in ROUND design, single-start or double-start, as standard for all G&G trapezoidal threaded spindles according to DIN 103 tolerance 7H and on request also as custom-made products.
For trapezoidal screw drives in continuous operation, the combination of steel spindle and gunmetal nut is recommended due to the favourable wear properties. Trapezoidal threaded nuts made of gunmetal have good emergency running characteristics, especially in the event of inadequate lubricant.
