Detail & Specs

External 12-Point metric flange bolts offer a good alternative to hex head bolts.
Class 12.9 Alloy Steel provides high tensile strength (170,000 psi). Greater torque can be applied to these bolts because of the 12-spline design, which provides more surface area for contact during tightening.
These bolts have a non-serrated, smooth-bottom flange with a reduced outer diameter, making them easy to install in tight spaces or bored holes. The underside of the flange surface ensures superior force distribution over a greater area, eliminating the need for a separate washer.
The non-indented head prevents grease and dirt from accumulating on the head, providing a higher quality finish and appearance.
Twelve point flange bolts can be used with many different styles of locking and non-locking nuts to clamp tightly to whatever the bolt is being used to secure. A 12-point wrench is used to install and tighten these bolts. A black oxide finish provides minimal corrosion resistance, best for indoor, dry environments. This finish is not suitable for outdoor applications, and will rust when exposed to moisture.
Also known as
Twelve spline flange bolt, ferry cap screw, flange screw with 12 external radial corners.
Use
Commonly used in heavy equipment applications, compact access spaces, industrial machinery, etc.
