S-94128A157 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior precision alignment with Class 3A thread fit ensuring secure, vibration-resistant connections in demanding applications
• Enhanced durability and wear resistance from alloy steel construction with Rockwell C32 hardness for long service life
• Accurate component positioning thanks to the 1/4" shoulder diameter with tight -0.001" to 0" tolerance for minimal play
• Reliable fine thread engagement with 10-32 UNF right-hand threads providing increased tensile strength in limited space
• Simplified installation and maintenance through slotted drive design enabling easy adjustment with standard tools
• Stable rotational performance from precisely machined 1/2" shoulder length with 0" to 0.005" tolerance control
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional value in applications requiring exact component alignment and rotational stability. The alloy steel construction with Rockwell C32 hardness withstands repeated assembly cycles and operational stresses in machinery, automation systems, and precision instruments. The Class 3A thread fit combined with 10-32 UNF fine threads creates secure fastening in thin materials and confined spaces, while the headless slotted design allows flush mounting in compact assemblies. The precisely controlled shoulder diameter and length tolerances eliminate play in rotating components, making these industrial shoulder screws ideal for pivots, axles, and guide pins where dimensional accuracy directly impacts performance and longevity.

Specification Summary & Compliance

This precision shoulder screw features 10-32 UNF right-hand threads with Class 3A fit for superior thread engagement. The shoulder maintains 1/4" diameter with -0.001" to 0" tolerance and 1/2" length with 0" to 0.005" tolerance for precise component positioning. Manufactured from alloy steel hardened to Rockwell C32, this component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for use in regulated industrial applications worldwide.
