S-93734A350 5/8"-11 x 2" Tension-Indicating Hex Head Screws

Key Features & Benefits at a Glance

• Visual tension confirmation at 17,000 lbs ensures precise clamping force and prevents under/over-tightening in critical assemblies.
• Exceptional strength and durability with Grade 8 classification, 150,000 psi tensile strength, and Rockwell C33 hardness for heavy-duty applications.
• Superior corrosion resistance from zinc yellow-chromate plated steel construction, extending service life in harsh industrial environments.
• Easy installation and high torque capability with external hex drive and 15/16" head width for secure tool engagement.
• Reliable thread engagement through UNC coarse threading and Class 2A fit, reducing cross-threading risks and ensuring consistent performance.
• Full threading along the 2" length provides maximum adjustability and load distribution across the entire fastener.
• Compliance with REACH regulations ensures environmental responsibility and suitability for regulated industries.

Professional Applications & Engineering Value

This Grade 8 tension indicating hex head screw delivers critical reliability in demanding applications where fastener failure is not an option. The zinc yellow-chromate plated steel construction provides excellent corrosion protection for outdoor equipment, structural steel connections, and heavy machinery exposed to moisture and chemicals. The UNC coarse thread design ensures rapid assembly and superior resistance to vibration loosening in industrial settings. With visual tension indication at 17,000 lbs, engineers can verify proper installation in critical joints for bridges, construction equipment, and high-stress mechanical systems, eliminating guesswork and reducing maintenance costs. The combination of 150,000 psi tensile strength and Rockwell C33 hardness makes it ideal for applications subject to dynamic loads and extreme pressure.

Specification Summary & Compliance

This 5/8"-11 hex head screw features Class 2A thread fit tolerances and UNC coarse threading per industry standards. Manufactured from high-strength steel with zinc yellow-chromate plating for corrosion resistance. The fastener is fully threaded along its 2" length with right-hand thread direction. Compliant with REACH (EC 1907/2006) regulations regarding substance restrictions, ensuring environmental safety and regulatory acceptance in industrial markets.
