Spring Bolts

McNaughtans spring bolts and latches secure doors, sideboards, tailgates and ramps on trucks, trailers and industrial vehicle bodies. The spring keeps the bolt engaged without any additional catch, and pulling the handle is enough to release it. The collection brings together zinc-plated spring bolts in different lengths and Ø12 mm steel pins.

How to choose a bolt or latch

Start with the diameter of the bolt and of the housing it enters, since excessive clearance lets the sideboard rattle on the move. Then check the overall length, which must leave enough travel to pass through both parts, and the bracket's fixing pattern. On outdoor mountings, a zinc-plated finish considerably extends the life of the spring.

  • Match the bolt diameter to the housing.
  • Check the length and the usable travel.
  • Review the bracket's fixing pattern.
  • Choose a zinc-plated finish for exposed mountings.

Frequently asked questions

Do they work as a security closure?

They hold the door or sideboard, but they take no key. Where access control is needed, they are combined with a lock.

How do I stop the bolt from seizing?

By cleaning the housing and lightly greasing the shaft at each service; most seizures come from accumulated dirt rather than from the spring.
