Description:
This two-pack of crank arm fixing bolts provides a dependable solution for securing bicycle crank arms to the bottom bracket spindle. Made from carbon steel and finished with a protective silver plating, these bolts resist rust and wear.
The added thread adhesive helps keep the bolt securely in place, reducing the risk of loosening due to vibration. A hard rubber cap is fitted over the head of each bolt to reduce weight, simplify installation, and contribute to sealing the bottom bracket area against contaminants like water, sand, or dirt.
Each bolt is machined with an internal 8mm hex drive for tool engagement. To install or remove, a standard 8mm hex key is required (sold separately).
These bolts are used in pairs to attach one crank arm assembly. Available in multiple sizes to suit a range of common bottom bracket types:
M8 x 15mm (5/16" x 19/32")
M10 x 14mm (3/8" x 9/16")
M12 x 14mm (1/2" x 9/16")
M15 x 15mm (5/8" x 19/32")
Please verify your current bolt size prior to ordering. Suitable for many square taper and splined bottom bracket systems.
