S-91263A887 M6 x 10 mm DIN 7991 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 10.9 rating (120,000 psi) for reliable performance in high-stress industrial applications.
• Superior corrosion resistance provided by zinc-plated alloy steel, extending service life in harsh environments.
• Precise metric threading (M6 x 1 mm coarse) ensures secure fastening and compatibility with standard metric components.
• Optimized flat head design with 90° countersink allows for flush mounting, reducing snagging and improving aesthetics.
• Hex drive (4 mm) enables easy installation and high torque application with common tools.
• Full threading offers maximum grip length and uniform load distribution along the fastener.
• Compliance with DIN 7991 and environmental standards (RoHS 3/REACH) guarantees quality and safe use in regulated industries.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M6 flat head screws deliver robust performance where precision and durability are critical. The zinc-plated alloy steel construction resists corrosion, making them ideal for machinery, automotive assemblies, and outdoor equipment exposed to moisture or chemicals. With a Class 10.9 strength grade and Rockwell C32 hardness, they withstand high vibrational loads and tensile stresses without failure. The fully threaded coarse pitch metric design ensures quick installation and secure hold in metals or composites, while the flat head with hex drive facilitates countersunk, low-profile connections that minimize protrusion risks. Adhering to DIN 7991, these screws provide consistent dimensional accuracy, reducing assembly errors and maintenance needs in heavy-duty fastening applications.
