Professional Applications & Engineering Value
This 8-32 UNC shoulder screw delivers critical engineering solutions where precise alignment and reliable fastening are paramount. Manufactured from alloy steel with Rockwell C32 hardness, it withstands high-stress conditions in machinery, automotive, and precision equipment. The Class 3A thread fit and coarse threading prevent loosening under vibration, while the headless slotted drive facilitates maintenance in confined spaces. Its precisely machined shoulder diameter (3/16") and length (1/4") act as a dependable pivot or spacer, eliminating misalignment in assemblies and reducing wear on connected components, thereby extending service life and minimizing downtime.
Specification Summary & Compliance
This shoulder screw features a right-hand UNC 8-32 thread with Class 3A fit for high precision. Shoulder dimensions include a diameter of 3/16" (tolerance: -0.001" to 0") and length of 1/4" (tolerance: 0" to 0.005") for exact assembly requirements. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial applications.
