• Enhanced grip and alignment from the extended tip design, providing reliable positioning for shafts and collars
• Wide industrial compatibility with UNC coarse threads and 5/8"-11 size, fitting standard components without modification
• Long-term operational reliability backed by compliance with ASME B18.3, RoHS 3, and REACH environmental standards
• Precision-engineered dimensions including controlled tip length and diameter tolerances for consistent performance in repetitive use

Professional Applications & Engineering Value

This 5/8"-11 UNC set screw is engineered to address common industrial challenges such as component slippage and misalignment in high-stress environments. Crafted from Black Oxide Alloy Steel, it offers excellent wear resistance and withstands harsh conditions, while the extended tip ensures secure contact with mating parts, reducing the risk of loosening under vibration. Ideal for securing pulleys, gears, and couplings in machinery, its Class 3A thread fit and coarse thread spacing provide quick assembly and reliable clamping force. The headless design with hex drive allows for flush mounting in confined spaces, making it a versatile choice for automotive, manufacturing, and heavy equipment applications where precision and durability are critical.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threading (5/8"-11) per industry norms. Manufactured in compliance with ASME B18.3 specifications, it ensures consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material integrity for global industrial use.
