Bolts with large thread pitch

Hedgecutter · 12-09-2018 02:26PM #1

Anyone know where i could pick up these bolts. Major dia is 6.17mm and the pitch is large at roughly 2mm.

Cant get them in standard builders shops

Looks like a self-tapper and the pitch wouldn't be important? Is it screwed into wood?

No, Metal housing that holds the working that open and close gates. Loos like cast iron, but im not 100% sure.

Image below shows motor connected to housing.

Thats just a self tapper

It's called a self tapping screw it that's any help.

Any large Self Taper would do if thats the case then. You dont need to maintain the pitch.

Alternatively drill through the gate and replace with nut and bolts through and through.

It’s a cap head self tapping screw.
