Duck oil is good then while you are about what type of bolts are used to connect rsj beams together.

Grade 8.8 bolts (most standard bolts stocked are 8.8), nothing special.
Finish usually BZP.
Unless the steel is galvanised then spun galv bolts are prefered.

Size wise, M12, M16, or M20 on domestic stuff. The SE will tell you what size is required.

No probs, thats what we are here for

Incase you wondered, normal hex head bolts, with full nuts and a plain washer on the nut side.
Unless its a special application, where countersunk ones may be required. they tend to come in grade 10.9/12.9
I say bolts, for most rsj/ub applications, set screws are required.
Set screws are threaded all the way to the underside of the head, bolts have a shank, and then thread on the end. Most people just call them bolts
