S-93339A250 M5 x 10 mm Set Screws

Key Features & Benefits at a Glance

• Superior holding power with Class 6g thread fit ensuring precise engagement and resistance to loosening under vibration
• Exceptional durability from alloy steel construction with Rockwell C39 hardness for long-term performance in demanding environments
• Easy installation and removal with 2.5mm hex drive design providing secure tool engagement without head protrusion
• Enhanced surface contact thanks to the ball tip design that minimizes component damage while maintaining firm positioning
• Reliable coarse threading with 0.8mm pitch for quicker assembly and reduced cross-threading risks in industrial applications
• Environmental compliance meeting RoHS 3 standards with exemption for lead as steel alloying element
• Metric precision with M5x10mm dimensions ensuring seamless integration into international engineering specifications

Professional Applications & Engineering Value

This alloy steel hex headless set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The ball tip design distributes pressure evenly across contact surfaces, preventing damage to expensive components while maintaining secure positioning in pulleys, gears, and collars. With Class 6g thread tolerance and coarse metric threading, installation becomes significantly faster while reducing the risk of cross-threading during high-volume assembly operations. The Rockwell C39 hardness ensures the screw maintains its mechanical properties under repeated stress cycles, making it ideal for automotive, machinery, and manufacturing applications where reliable fastening cannot be compromised. The headless configuration allows for flush mounting in tight spaces where protruding fasteners would interfere with adjacent components.

Specification Summary & Compliance

This metric set screw features M5x0.8mm coarse threading with Class 6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The 10mm length and 2.5mm hex drive provide consistent performance across industrial applications. Manufactured from alloy steel with Rockwell C39 hardness, the screw meets rigorous mechanical requirements. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead as an alloying element in steel, confirming its suitability for regulated industries and international supply chains.
