Drive shaft loop bolts

[stagea]

I have bought a couple of drive shaft loop kits. It comes with 4 M8 bolts each side for fixing to the floor. Is this an acceptable alternative to 2 M10 bolts each side or should I just use 2 of the 4 holes each side and drill out to M10?

Hi there

It really depends on the space available to you for the installation, but I would expect it would be easier to use two 10mm bolts per side. If you decided to go with four smaller fasteners, you'd need to use a minimum of three 8mm bolts. If you're fitting a loop to a floor pan, you'll need to use doubler plates which have a minimum mating area of 3000 square mm, and are as close to square as can be practically achieved.

Specification change - the minimum material specification has been reduced from 6mm to 5mm. We know that some off the shelf loops are still less than 5mm though, so make sure you check it first.

There's also an infosheet available which might provide some help; www.lvvta.org.nz/documents/infosheets/LVVTA_Info_09-2011_Drive-shaft_Safety_Loop_Requirement_Clarification.pdf

I hope this helps

Cheers, Justin
