Hex head or some head bolts for trunking

Baldyhugh
Hi


Im currently nearing completion of a steel trunking job and was looking for some advice. The 3x3 steel trunking is fixed on top of unistrut running perpendicular to it at regular intervals. I used M10 zebedees and hex head bolts for this. I now wondered if I should have used dome head bolts instead for the same reason as M6 dome head bolts are used to bolt the trunking together - to protect the cable. Was just wondering what others use in this circumstance


Thanks

    M10 Hex heads holding trunking down on Unistrut is perhaps a bit of overkill


    More traditionally would be M6 Slotted Dome heads (ie gutter bolts)


    Assuming you don't need a lump hammer to put the lid on, and you take a bit of care when installing cabling, I wouldn't have any reservations about hex heads showing inside the trunking
