Description
The ANSI/ASME B18.2.7.1M Metric 12-Spline Flange Screws are engineered for applications requiring high torque strength, secure fastening, and optimal load distribution. The 12-spline head design allows for higher torque transmission compared to hex fasteners, offering compact installation and easy accessibility in tight spaces. The integrated flange head reduces the need for a separate washer, ensuring even pressure distribution and resistance to loosening from vibration.
Manufactured from high-quality carbon steel or stainless steel, these screws are available in various strength grades including 4.8, 8.8, 10.9, and 12.9, suitable for demanding mechanical, structural, and automotive tasks.
Multiple surface finishes are offered for enhanced durability and corrosion protection, such as plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation.
Fully compliant with ANSI/ASME B18.2.7.1M (R2009) and also compatible with GB, DIN, ISO, ASTM, BS, JIS, these screws are available in OEM custom designs as per customer drawings or samples. Free samples are available upon request. Secure packaging options include wooden boxes, pallets, cartons, plastic or nylon bags.
