Professional brake bleed fittings for commercial or occasional use. These brake bleed screws feature a 7mm x 1mm bleedscrew size and are accurately machined to prevent air/fluid leakage. Manufactured from steel for strength and durability, they have a hex head for easy installation or removal with a spanner or deep socket. The total length of the thread under the hex is 10mm. These are suitable to fit on 5mm pipes, which is the pipe for bleeding the brakes above the hex. This pack contains 4 pieces.
