An additive in the abrasive resists heat.

A coating prevents dust and debris from building up on the abrasive surface.

Mount these knobs into a threaded hole. They provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.

Bonded to the stud is an acrylic adhesive that adds friction to resist loosening from vibration. Use these knobs to position, tighten, and hold fixtures, equipment, and machinery. They mount into a threaded hole.
