S-99642A190 M10 x 20 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with precision cup point design that bites into mating surfaces to prevent component slippage
• Exceptional durability from alloy steel construction with Rockwell C45 hardness for reliable performance in demanding applications
• Precise installation control with 5mm hex drive that provides secure tool engagement and prevents stripping during high-torque applications
• Consistent thread engagement with Class 5g6g thread fit ensuring reliable fastening and vibration resistance in fine-thread applications
• Broad industrial compatibility with M10 x 1.25mm fine metric thread pattern that meets DIN 916/ISO 4029 specifications
• Environmental compliance assurance with RoHS 3 and REACH compliance for use in regulated industries worldwide
• Space-saving headless design that allows for flush mounting in applications where protruding fastener heads are not feasible

Professional Applications & Engineering Value

This M10 set screw delivers critical engineering value in applications requiring secure axial positioning of components on shafts, spindles, and collars. The alloy steel construction with Rockwell C45 hardness provides exceptional resistance to wear and deformation under constant rotational forces. The fine thread pitch of 1.25mm offers superior vibration resistance compared to coarse threads, making it ideal for precision machinery, motor assemblies, and power transmission systems. The cup point tip creates concentrated pressure that digs into mating surfaces, preventing relative movement even under substantial torque loads. With its headless design and 5mm hex drive, this fastener solves space-constrained installation challenges while maintaining high clamping force in industrial equipment, automotive components, and manufacturing jigs.

Specification Summary & Compliance

This metric set screw features precise M10 x 1.25mm fine threading with Class 5g6g thread fit tolerance according to ISO standards, ensuring consistent engagement and reliable performance. Manufactured to meet DIN 916 ISO 4029 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in regulated industries and international markets.
