S-91280A084 M8 x 25 mm ISO 4017, DIN 933 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior load-bearing capability with Class 8.8 strength grade and 110,000 psi tensile strength for reliable performance in demanding applications
• Enhanced corrosion resistance and durability provided by the steel construction with Rockwell C21 hardness
• Easy installation and removal with standard external hex drive and 13mm head width for common tool compatibility
• Secure fastening in various materials thanks to the coarse M8x1.25 thread pitch and Class 6g thread fit
• Maximum grip and holding power achieved through fully threaded 25mm length design
• Global compliance assurance meeting ISO 4017 DIN 933 standards for consistent quality and interchangeability
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance for sustainable operations

Professional Applications & Engineering Value

These M8 hex head screws deliver exceptional engineering value in industrial settings where vibration resistance and structural integrity are critical. The Class 8.8 steel construction provides the optimal balance between strength and ductility, preventing brittle failure under dynamic loads. The coarse thread pitch (1.25mm) ensures rapid installation and superior performance in softer materials or where frequent disassembly is required. With fully threaded design and right-hand threading, these fasteners maintain consistent clamping force across the entire 25mm length, making them ideal for machinery assembly, structural frameworks, and equipment manufacturing where high tensile strength and reliable performance are non-negotiable requirements.

Specification Summary & Compliance

This metric hex head screw features precise M8x1.25 coarse threading with Class 6g thread fit tolerance per ISO standards. Manufactured to ISO 4017 DIN 933 specifications, the fastener ensures dimensional accuracy and interchangeability. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial applications while meeting stringent material restriction requirements.
