S-90657A106 M3 x 10 mm DIN 920 Steel Cheese Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• High tensile strength of 60,000 psi ensures reliable fastening under mechanical stress and vibration
• Precision Class 6g thread fit guarantees smooth installation and consistent engagement with mating components
• Partially threaded design allows for controlled clamping force and secure positioning in assembly applications
• Narrow rounded cheese head profile provides a low-profile finish while the slotted drive enables quick tool compatibility
• Compliance with DIN 920 standards ensures dimensional accuracy and interchangeability in metric fastener systems
• Rockwell B71 hardness rating offers excellent wear resistance and durability for repeated use

Professional Applications & Engineering Value

Engineered for precision assembly, this M3 x 0.5 mm coarse thread screw addresses common challenges in electronics, machinery, and automotive sub-assemblies where space constraints and vibration resistance are critical. The zinc-plated steel material provides a protective barrier against oxidation, while the partially threaded shank allows unthreaded sections to act as precision guides or pivot points. With a rounded cheese head and slotted drive, it facilitates quick installation in tight spaces without protruding excessively, reducing snag risks in moving parts. The Class 6g thread fit and flat tip ensure accurate alignment and prevent cross-threading, minimizing assembly errors and rework in high-volume production lines.

Specification Summary & Compliance

This screw adheres to DIN 920 specifications with a Class 6g thread tolerance, M3 x 0.5 mm coarse thread, and dimensions including a 4 mm head diameter and 10 mm length. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety compliance for global industrial supply chains.
