Features of Accusize 6780-1044 CAT40 Retention Knob with Coolant Hole
-
High-Strength Alloy Construction
Manufactured from 20CrMnTi alloy steel, the pull studs undergo heat treatment and are hardened to HRC 58, providing exceptional strength, wear resistance, and durability.
-
Magnetic Particle Inspection for Crack-Free Integrity
Each retention knob undergoes individual magnetic particle inspection to ensure it is free from cracks or material defects. This non-destructive testing method verifies the structural integrity and reliability of the knob, providing confidence in its performance under high loads and extreme conditions.
-
Precision Ground Mating Surfaces for Superior Fit
All mating surfaces are precision ground to tight tolerances, ensuring a perfect fit and optimal contact. This process enhances the retention knob's stability and accuracy when installed, minimizing wear and maintaining consistent performance over time.
-
Precision Machined Puller
The load-bearing and non-load-bearing surfaces are machined in a single operation to ensure dimensional accuracy and achieve a high-quality surface finish.
-
Optimized Flange Design
The flange section features a fully blackened finish, with the milled surfaces precisely machined using specialized equipment to ensure a smooth, burr-free finish.
-
Enhanced Precision Threading
The threads are machined post-carburizing and quenching, ensuring high accuracy, increased durability, and enhanced resistance to corrosion.
