01 / THE COMPONENT

More than a threaded connection.

  • Head and drive geometry reviewed alongside the installation method.
  • Stepped shanks, shoulders and other functional features defined by the drawing.
  • Thread length and fit considered together with the unthreaded dimensions.

03 / BEFORE WE MAKE IT

The right details
from the start.

A clear drawing helps us focus the review. These are the details most useful for your bolts inquiry.

  • Head style, drive detail and overall or under-head length.
  • Thread designation, fit, runout and required threaded length.
  • Material or property-class requirements and any specified surface treatment.
  • Your drawing revision, expected quantity and target delivery date.

Materials reviewed include SAE 1008–1045 steels, 10B21, SCM435, stainless steel and brass. Suitability is confirmed for the individual component.
