Hexagonal flange screws M10*16

Hex flange screws M10x16, also referred to as M10x16 flange bolts, comply with DIN 6921 standards. These DIN 6921 flange screws feature a hexagonal head with an integrated washer for enhanced load distribution. Ideal for automotive, machinery, and structural applications, they provide secure fastening in high-vibration environments. Available in steel or stainless steel with zinc-plated or galvanized finishes.

Specification

SEODescription

Hex flange screws M10x16, also known as M10x16 flange bolts or DIN 6921 flange screws, are standardized fasteners featuring a hexagonal head with an integrated washer-like flange (typically 24mm diameter). Designed for M10 threads with 16mm shaft length, they eliminate the need for separate washers, providing high clamping force and vibration resistance. These screws are commonly manufactured in steel grades 8.8 or 10.9, with optional zinc plating or hot-dip galvanizing for corrosion protection. Suitable for temperatures ranging from -50°C to +300°C depending on coating, they're widely used in automotive assemblies, machinery manufacturing, and structural applications. Key advantages include simplified installation and reduced loosening risks, though their bulkier profile may require precise clearance. Compliance with DIN 6921 ensures compatibility with standard wrenches (17mm across flats) and torque specifications (typically 57-67 Nm for grade 8.8).
