S-91390A132 M6 x 16 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Rockwell C45 hardness alloy steel construction, resisting wear and deformation under high-stress conditions.
• Secure, non-slip fastening thanks to the cup tip design, which bites into surfaces for a reliable, vibration-resistant grip.
• Precise and reliable thread engagement ensured by the Class 5g6g thread fit, providing consistent performance in metric assemblies.
• Streamlined installation in confined spaces with its headless, hex drive design, allowing for a flush finish and easy access with a 3 mm hex key.
• Broad compatibility and interchangeability by conforming to DIN 916 / ISO 4029 standards, ensuring quality and fit in global engineering applications.
• Durable, long-term performance from the coarse (M6x1 mm) thread, which is less prone to clogging and ideal for rapid assembly.
• Safe for use in regulated industries as it is fully RoHS 3 and REACH compliant, meeting strict environmental and safety standards.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical challenges in precision assembly and machinery. Manufactured from high-strength alloy steel, it provides the necessary durability to prevent loosening in high-vibration environments, such as motor mounts, gear assemblies, and precision tooling. The headless design with a 3 mm hex drive allows for a clean, flush installation where protruding fastener heads are not feasible. The cup tip concentrates pressure on a small contact area, creating a superior grip on shafts and components, which is vital for set screw applications requiring zero slippage. Combined with its metric coarse thread and right-hand direction, it ensures quick, secure fastening, reducing assembly time while enhancing the reliability of your mechanical systems.

Specification Summary & Compliance
