hammerhead tbolts manufacturing ukCase Study

A recent project, for a client in Europe, was the production of hammerhead bolts to DIN 7992 in grade 10.9 material, finished in black oxide. Sizes M48 to M100 and lengths from 1900MM to 3100MM.

Forged on site at our manufacturing facility in Stourbridge, West Midlands, special lifting jigs were put in place to assist the forging operators. With the average bolt forging weighing 135KG, safety was of upmost importance.

The ends were drilled and tapped M16x32MM, to enable the use of lifting eyebolts when moving the bolts on site. The ends also included directional slots, used as a visual aid during installation.

Testing was carried out to customer specifications. This included Ultrasonic, Magnetic and Liquid Dye Penetrant examination as well as Brinell and Charpy testing.

A complete Quality plan was provided for each bolt size, a strict requirement, ensuring full tractability for every stage of production.
