S-96755A445 M8 x 35 mm ISO 4017, DIN 933 Medium-Strength Metric Class 8.8 Steel Thread-Locking Hex Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking thanks to the permanent nylon patch that maintains secure fastening even under extreme temperature fluctuations from -55° to 250°F
• Superior torque transmission with the external hex drive and hex head design, allowing for efficient installation with standard tools in high-torque applications
• High tensile strength and durability from Class 8.8 rating and zinc-plated steel construction, providing reliable performance under loads up to 110,000 psi
• Consistent thread engagement with fully threaded M8 coarse thread (1.25mm pitch), ensuring maximum grip and load distribution across the entire length
• Enhanced corrosion resistance through zinc plating, extending service life in harsh industrial environments
• Precision manufacturing with Class 6h thread fit, delivering reliable dimensional accuracy and compatibility with standard metric components
• Broad industrial applicability due to compliance with ISO 4017, RoHS 3, and REACH standards, making them suitable for regulated sectors

Professional Applications & Engineering Value

Engineered for demanding environments, these M8 hex head screws address critical challenges in industrial fastening where vibration loosening and material fatigue are common failures. The zinc-plated steel construction provides essential corrosion protection, while the Class 8.8 strength grade ensures structural integrity under high stress. The nylon patch thread locker offers a permanent locking solution that eliminates the need for secondary adhesives, maintaining clamp load in automotive, machinery, and construction applications. With fully threaded coarse pitch design, they facilitate quick assembly and uniform stress distribution, reducing the risk of joint failure in dynamic load conditions.
