Banjo Bolt (BSPP)

The banjo fitting is only as good as the bolt clamping it down.

A banjo joint is a sandwich: fitting between two crush washers, drawn tight by a drilled bolt that also carries the flow. The Finish Line Factory Banjo Bolt (BSPP) is that bolt, in bspp thread pitches from 1/4x19BSPP thread up, with head sizes and lengths matched to real-world banjo hardware. Fresh bolt, fresh washers, sealed joint.

Benefits

• The joint draws down evenly and stops weeping after the first heat cycle
• Thread pitch actually matches the component, no guessing at the parts store
• Head and length options cover stacked double-banjo assemblies too
• Replacing a stretched or rounded original bolt takes minutes

Features

• Hollow drilled banjo bolt carrying flow through the joint
• BSPP thread options: 1/4x19BSPP thread
• Head sizes: 17.45mm Head...
• Lengths (OAL x UHL) to suit single and stacked fittings
• Secures banjo fittings and adapters to their connections
• Sold as a single bolt

The Details

Banjo joints seal on their crush washers, not on threads, which changes the rules: new washers at every assembly, clean flat mating faces, and torque sufficient to crush the washers evenly without stretching the bolt. The bolt itself is hollow with cross-drilled passages, so flow rides through it; match the thread precisely, because a near-miss pitch will thread in and then strip out under torque. Length matters as much as thread: too short and engagement suffers, too long and the bolt bottoms before the washers crush. Stacked double-banjo setups need the longer under-head lengths listed. Pair with FLF aluminum crush washers in the matching sizing and the joint seals the way banjo joints are supposed to.
