SPS Technologies Offers Large Diameter 8-Pitch Locknuts That Meet Military Specifications

October 30, 2004

JENKINTOWN, PA. – SPS Technologies offers a line of 8-pitch, large-diameter locknuts that met the locking torque requirements of NASM-25027 (formerly MIL-N-25027). Designed originally for the petroleum industry, these one-piece, all-metal locknuts offer vibration-resistant locking without the excessive wrenching torques needed to tighten nuts with more threads per inch.

Sizes from 1” diameter to 2-1/2” diameter are available in carbon steel or corrosion-resistant austenitic steel. Cadmium plating to QQ-P-416 and silver plating per AMS 2410 are applied in the SPS in-house computer controlled plating facility. Every thread in the one-piece design carries a portion of the induced load, allowing these locknuts to offer reliability under the severe conditions experienced by heavy drilling and pumping equipment.
