Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI for reliable performance in high-stress and heavy-duty applications.
- Superior corrosion resistance provided by the black-oxide finish, extending service life in harsh industrial environments.
- High hardness rating of Rockwell C37 ensures excellent wear resistance and durability under repetitive loads.
- Precise left-hand threading (M4 x 0.7mm coarse) for secure fastening in specialized assemblies requiring reverse-thread direction.
- Standard hex socket drive (3mm) allows for easy installation with common tools, reducing assembly time and effort.
- Full threading along the 16mm length offers maximum grip and uniform clamping force across the entire engagement area.
- Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability for global engineering projects.
Professional Applications & Engineering Value
This Class 12.9 alloy steel socket head cap screw is engineered to address critical challenges in demanding industrial settings. Its left-hand metric thread (M4 x 0.7mm coarse) is specifically designed for applications where reverse threading prevents loosening due to rotational forces, such as in machinery with counter-rotating parts. The black-oxide surface treatment provides a durable barrier against rust and corrosion, making it ideal for use in automotive, aerospace, and manufacturing equipment exposed to moisture or chemicals. With a fully threaded design and high tensile strength, it ensures consistent clamping pressure and resists vibration-induced failure, reducing maintenance needs and enhancing operational safety in heavy-duty assemblies.
Specification Summary & Compliance
This screw features M4 x 0.7mm coarse threads with a Class 5g6g thread fit for precise dimensional tolerance. It is manufactured in accordance with DIN 912 and ISO 4762 specifications, ensuring consistent quality and global compatibility. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, supporting sustainable and safe usage in various industries.
