S-90665A136 10-32 x 1/2" ASTM A574 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance with zinc plating protects against rust and extends service life in harsh industrial environments.
• Precise Class 3A thread fit provides tight, secure connections with minimal play, enhancing assembly accuracy and vibration resistance.
• Low-profile socket head design allows for installation in confined spaces while maintaining high torque capability with a 3/32" hex drive.
• Fully threaded construction offers consistent clamping force along the entire 1/2" length for uniform load distribution.
• High hardness rating (Rockwell C39) ensures excellent wear resistance and durability under repeated use.
• Compliance with international standards including ASTM A574, RoHS 3, and REACH guarantees material quality and environmental safety.

Professional Applications & Engineering Value

These 10-32 UNF low socket head cap screws are engineered to address critical challenges in precision assemblies where space constraints and vibration resistance are paramount. The zinc-plated alloy steel construction provides robust corrosion protection for machinery, automotive, and electronics applications exposed to moisture or chemicals. The fine thread spacing and Class 3A fit deliver superior clamping force and prevent loosening in dynamic environments, while the low-profile head design enables flush mounting in compact designs. Ideal for securing components in jigs, fixtures, and high-performance equipment, these fully threaded fasteners ensure consistent engagement and reliable performance under loads up to 140,000 psi, minimizing maintenance needs and downtime.

Specification Summary & Compliance

Manufactured to precise dimensional standards, these screws feature UNF fine threads with a Class 3A thread fit for high accuracy and interchangeability. The 1/2" length and fully threaded rod type provide uniform engagement. Compliance includes ASTM A574 specification for alloy steel socket head cap screws, ensuring material integrity and mechanical properties. Environmental regulations met: RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant (as of 01/17/2023 for SVHC id=233), confirming restricted substance adherence for global supply chains.
