1/4″ x 28 Special Taper Thread Forming Thread. Hydraulic 90° Grease Fitting.
Zinc Trivalent Passivate Finish. RoHS and REACH Compliant.
Self-forming threads can be screwed or driven into an untapped hole. The recommended size of the hole for a 1/4 x 28 thread is 5.84-5.97mm (Ref SAE J534) but can be dependent on the material.
Avoid chamfering the hole, as a sharp edge to the hole helps the thread bite.
Also available with Zinc Yellow Chromate Finish. Code Number 415590. Limited Availability.
