S-93339A251 M5 x 16 mm Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 6g thread fit for reliable, vibration-resistant fastening in demanding applications.
• Exceptional durability thanks to alloy steel construction and Rockwell C39 hardness, resisting wear and deformation under high stress.
• Easy installation and removal with a 2.5 mm hex drive, allowing for efficient tool engagement in confined spaces.
• Precise alignment and reduced surface damage from the precision ball tip, ensuring smooth contact and minimal marring on components.
• Wide compatibility with coarse M5x0.8 mm metric threads, making it ideal for standard industrial assemblies and replacements.
• Environmental compliance with RoHS 3 regulations, supporting safe and sustainable manufacturing practices.
• Space-saving headless design for flush mounting in applications where protrusion must be avoided.

Professional Applications & Engineering Value

This M5 set screw is engineered from alloy steel to address common industrial challenges such as component slippage and loosening under dynamic loads. The Class 6g thread fit ensures precise engagement with mating parts, reducing the risk of thread stripping in high-vibration environments like machinery and automotive systems. Its ball tip design minimizes stress concentration on contacted surfaces, preventing indentation and enabling smoother adjustments in precision equipment. With a hex drive and headless profile, it offers easy access in tight spaces while maintaining a low profile for streamlined assemblies. Ideal for securing gears, pulleys, and collars, this metric set screw delivers consistent performance in applications demanding high strength and reliability, supported by its coarse thread for quick installation.

Specification Summary & Compliance

This set screw adheres to metric standards with an M5x0.8 mm coarse thread and Class 6g tolerance for precise fit. It meets RoHS 3 (2015/863/EU) compliance under exemption 6(a) for lead as an alloying element in steel, ensuring environmental safety. Manufactured with a right-hand thread direction and a 16 mm length, it is designed for consistent performance in industrial settings.
