S-91390A163 M10 x 30 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with cup point design that bites into mating surfaces for maximum resistance to loosening under vibration and load
• Exceptional strength and durability from high-grade alloy steel heat-treated to a Rockwell C45 hardness, ensuring long-term performance in demanding applications
• Precise and reliable fit with Class 5g6g thread tolerance, guaranteeing consistent engagement and reducing the risk of cross-threading during installation
• Optimized for high-torque assembly featuring a 5mm internal hex drive that provides a secure tool grip and minimizes drive head stripping
• Broad industrial compatibility due to compliance with DIN 916/ISO 4029 standards, ensuring interchangeability and meeting European engineering specifications
• Safe for regulated environments as it is fully compliant with RoHS 3 and REACH regulations, containing no hazardous substances
• Efficient installation with a coarse (1.5mm pitch) right-hand thread that enables faster driving and reduced assembly time compared to fine-pitch alternatives

Professional Applications & Engineering Value

This M10 set screw is engineered to address critical challenges in precision machinery, automotive components, and heavy-duty industrial equipment. The alloy steel construction, combined with Rockwell C45 hardness, provides the necessary shear and tensile strength to prevent failure under cyclic stresses. The cup point design concentrates pressure on a small area, creating a permanent indentation for a vibration-resistant lock that secures gears, pulleys, and collars on shafts without slipping. Its headless and hex drive profile allows for flush mounting in confined spaces, making it ideal for applications where protruding fasteners are not feasible. Fully compliant with DIN 916/ISO 4029 standards, this metric set screw ensures dimensional consistency and reliability in OEM and MRO operations, reducing maintenance downtime and enhancing assembly integrity.

Specification Summary & Compliance

This set screw features an M10 x 1.5mm coarse metric thread with a Class 5g6g thread fit, ensuring precise dimensional accuracy per ISO standards. It is manufactured to meet DIN 916 ISO 4029 specifications, guaranteeing consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe use in various industrial sectors.
