S-90666A113 M4 x 8 mm DIN 7984 Super-Corrosion-Resistant 316 Stainless Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Space-saving low-profile head design provides a flush finish in tight clearance applications
• High tensile strength of 70,000 psi ensures reliable, vibration-resistant fastening in demanding mechanical assemblies
• Precision Class 6g thread fit guarantees smooth installation and consistent clamping force
• Fully threaded shank allows for maximum adjustability and uniform load distribution along the entire length
• 2.5mm hex drive compatibility offers secure tool engagement and reduced risk of cam-out during torque application
• Compliance with DIN 7984 ensures dimensional accuracy and interchangeability with other standard components

Professional Applications & Engineering Value

This M4 low profile socket head cap screw is engineered to address critical challenges in precision machinery, electronics enclosures, and automotive subsystems where space constraints and corrosion are primary concerns. The 316 stainless steel material provides exceptional resistance to chlorides and acidic conditions, significantly extending service life in marine, chemical processing, and outdoor applications. The low-profile socket head minimizes protrusion, preventing interference in compact assemblies while the coarse 0.7mm thread pitch enables quicker installation and reduced cross-threading risks compared to fine-thread alternatives. With its fully threaded design and hex drive, it delivers uniform stress distribution and reliable torque transmission, making it an optimal choice for vibration-prone equipment requiring maintenance-free performance.

Specification Summary & Compliance

This metric fastener features M4 x 0.7mm coarse threads with Class 6g tolerance for precise fit, and is manufactured to DIN 7984 specifications ensuring dimensional consistency. The screw maintains 70,000 psi tensile strength and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial supply chains requiring verified material safety and sustainability standards.
