Pull Stud - Retention Knob Section
CDTooling retention knobs are manufactured from hot-rolled 8620H fine grain steel.
They are shot penned to relieve stress, and hard turned or superior fit and finish.
Our knobs are laser marked with the date of purchase to help determine life span.
For tractability purposes, each knob is lasered with a part number, serial number, and lot number.
All of our knobs are made in the USA from USA manufactured materials.
We stock over 400 different styles of retention knobs including adapters for NMTB toolholders.
Retention knobs come packaged in individual containers with identification prints on each container.
Retention knobs should be inspected yearly for cracks and wear, and replaced every three years.
(Based on a 40 hour week under normal conditions.)
