S-93615A453 5/16"-18 x 3/4" 18-8 Stainless Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh or outdoor industrial environments.
• Exceptional thread reliability with Class 3A fit, ensuring precise engagement and reduced risk of cross-threading in assembly.
• High tensile strength of 70,000 psi provides dependable load-bearing capacity for critical mechanical connections.
• Low-profile head design saves space in compact assemblies while maintaining a secure 5/32" hex drive for easy installation.
• Fully threaded shank offers consistent clamping force along the entire 3/4" length for uniform stress distribution.
• Coarse UNC threads enable faster installation and are less prone to clogging in dirty or debris-filled applications.
• Compliance with RoHS 3 and REACH ensures environmental safety and meets international regulatory standards for industrial components.

Professional Applications & Engineering Value

This low profile socket head cap screw is engineered to address common challenges in precision machinery, automation systems, and structural frameworks where space constraints and corrosion are primary concerns. The 18-8 Stainless Steel material provides excellent resistance to oxidation and chemical exposure, extending service life in demanding conditions such as marine, food processing, or chemical handling equipment. The Class 3A thread fit and coarse UNC threading ensure rapid, secure fastening with minimal risk of stripping, while the fully threaded design distributes load evenly, preventing joint failure under vibration or dynamic stresses. Its low-profile head is particularly valuable in applications with limited clearance, such as enclosures, jigs, and fixtures, without compromising the torque capability of the 5/32" hex drive.

Specification Summary & Compliance

This fastener adheres to UNC coarse thread standards with a precise Class 3A thread fit for high-tolerance assemblies. Dimensions include a 5/16"-18 thread size, 3/4" length, 0.438" head diameter, and 0.158" head height. Manufactured from 18-8 Stainless Steel with a hardness of Rockwell B70 and 70,000 psi tensile strength, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial supply chains.
