S-97050A175 M12 x 40 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in critical assemblies.
• Black-oxide coating on alloy steel provides superior corrosion resistance, extending service life in harsh industrial environments without compromising structural integrity.
• Low-profile socket head with hex pilot recess allows for easy installation in confined spaces while maintaining secure tool engagement and minimizing stripping.
• Class 10.9 strength rating and Rockwell C32 hardness deliver consistent durability and fatigue resistance, ideal for repetitive load applications.
• Partially threaded M12 x 1.75mm coarse pitch design offers optimal grip and vibration resistance, speeding up assembly in machinery and structural frameworks.
• Precision DIN 6912 compliance guarantees dimensional accuracy and interchangeability, ensuring seamless integration with standardized metric components.
• RoHS 3 compliance supports environmental and safety regulations, making these screws suitable for global supply chains and regulated industries.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M12 socket head cap screws address common challenges like space constraints and vibrational loosening. The low-profile head and hex with pilot recess enable secure fastening in compact assemblies, such as automotive engines or CNC machinery, where clearance is limited. Made from black-oxide alloy steel, they resist rust and wear in humid or abrasive conditions, reducing maintenance downtime. The Class 10.9 strength and coarse thread spacing ensure reliable clamping force in high-vibration applications, from conveyor systems to heavy equipment, while the partially threaded design concentrates stress effectively for enhanced joint stability.

Specification Summary & Compliance

This screw adheres to DIN 6912 standards, with a Class 6g thread fit for precise metric tolerances. It features a right-hand thread with a 1.75mm coarse pitch, 40mm length, and 30.5mm minimum thread length. Compliance includes RoHS 3 (2015/863/EU) for hazardous substance restrictions, ensuring suitability in electronics and industrial manufacturing.
