S-99642A130 M8 x 8 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with the cup point design that bites into materials for secure, vibration-resistant fastening in dynamic industrial environments.
• Exceptional durability and wear resistance thanks to the high-strength alloy steel construction and Rockwell C45 hardness, ensuring long service life under heavy loads.
• Precise and reliable thread engagement with the fine 1mm pitch and Class 5g6g thread fit, providing excellent alignment and reduced risk of cross-threading.
• Easy installation and removal using a standard 4mm hex key, offering a secure drive that minimizes tool slippage and damage in confined spaces.
• Guaranteed quality and interchangeability through compliance with DIN 916 and ISO 4029 standards, ensuring consistent performance and fit in metric assemblies.
• Safe for regulated industries as it is fully RoHS 3 and REACH compliant, meeting strict environmental and health standards for global use.
• Space-saving headless design that allows for flush mounting, ideal for applications where protrusion is not permissible.

Professional Applications & Engineering Value

This M8 x 1mm fine thread set screw is engineered to address critical challenges in precision assemblies, such as securing collars, gears, and pulleys on shafts without slipping. The alloy steel material, combined with Rockwell C45 hardness, provides high tensile strength and resistance to deformation under torsional stress. The cup point concentrates force to create a permanent indentation, enhancing grip on hardened shafts and preventing loosening from vibrations. Its headless and hex drive design ensures easy access in tight spaces, making it a reliable choice for machinery, automotive, and automation systems where metric thread accuracy and durability are paramount.
