Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with Class 10.9 tensile strength (140,000 PSI) for reliable performance in high-stress applications
- Superior corrosion resistance due to black-oxide coating on alloy steel, extending service life in harsh industrial environments
- Optimized installation efficiency with hex drive design and 2.5mm drive size for secure tool engagement and reduced assembly time
- Enhanced thread engagement through coarse 0.7mm pitch and Class 6g thread fit, ensuring vibration resistance and stable fastening
- Consistent dimensional accuracy maintained through full compliance with ISO 7380 manufacturing standards
- Reduced maintenance requirements thanks to Rockwell C32 hardness providing excellent wear resistance and durability
- Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe use across global markets
Professional Applications & Engineering Value
This M4 metric screw delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction combined with Class 10.9 strength rating prevents fastener failure in heavy machinery, automotive assemblies, and industrial equipment subjected to dynamic loads. The fully threaded design with coarse 0.7mm pitch ensures rapid installation and superior holding power in both metallic and composite materials. The rounded head profile with hex drive facilitates access in confined spaces while providing sufficient bearing surface. These industrial screws effectively address common challenges of corrosion-induced degradation and thread stripping, making them ideal for OEM manufacturing and maintenance operations requiring reliable metric fasteners.
Specification Summary & Compliance
Manufactured to precise ISO 7380 specifications with Class 6g thread fit tolerance ensuring dimensional consistency. The fully threaded M4 x 0.7mm configuration with 40mm length provides uniform stress distribution. Compliance verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming absence of restricted substances. Mechanical properties include Rockwell C32 hardness and 140,000 PSI tensile strength per Class 10.9 requirements.
