S-91152A113 0.375" ID Leveling Washers for I-Beams

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized iron coating for extended service life in harsh industrial environments
• Progressive load distribution thanks to the tapered design (0.313" to 0.141" thickness) that prevents surface damage and maintains joint integrity
• Precise fit and alignment with 0.375" inner diameter specifically engineered for 5/16" screw applications
• Enhanced durability with Rockwell B62 hardness rating that withstands heavy loads and repeated stress
• Optimal surface coverage provided by the 1" width for better load distribution and vibration resistance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use across global markets
• Dimensional stability maintained through inch system manufacturing precision for reliable performance

Professional Applications & Engineering Value

This hot-dipped galvanized iron tapered washer delivers exceptional engineering value by solving critical industrial fastening challenges. The tapered design (0.313" to 0.141" thickness gradient) effectively compensates for uneven surfaces and misaligned joints, preventing premature fastener failure in heavy machinery, structural steel connections, and equipment assembly. The galvanized iron construction provides superior corrosion resistance for outdoor applications, manufacturing facilities, and marine environments where moisture and chemicals are present. With precise 5/16" screw size compatibility and Rockwell B62 hardness, this industrial-grade washer maintains clamping force under vibration and dynamic loads, making it ideal for construction, automotive, and infrastructure projects requiring reliable, long-term fastening solutions.
