M16 16mm Tow Bar Bolts, Nuts and Spring Steel Washers

Simply Pick The Length Required From Options List. (Sold in Pack Of Two)

Bolts and Nuts are Zinc Coated Grade 8.8mm and come from a very good UK Supplier.
These are suitable for holding on your drawbar , towing eye.

When you measure up for these Bolts - We recommend that you consider the width of the nuts, washer
 and allow for a minimum of x

TWO threads sticking through the nuts - the thread pitch is 2mm - so 4mm for two full threads

Nut thickness is 13mm and washer thickness 1.5mm.

NOTE: Tow Bar Bolts use a 'friction grip' type arrangement, which relies on the pre-load applied to the bolt to hold the component

forces together using the friction between the components.

We recommend tightening them up using a torque wrench - used on the nut end

NOTES:

Please do not be tempted to fit Stainless Steel Bolts for this application - Although Stainless Is "Pretty" - It does not have the same Tensile Strength of these High Tension Bolts.
I buy my Bolts from a Recognized UK Supplier - Quality is important for this type of application.
No Need To go to 10.9 grade Bolts - Unless You are towing more than 10 tons! - Even with a Land Rover this is highly unlikely.
The Diameter and Quality of this bolt has been worked out by "Proper Engineers" with calculations that would blow away the average man.
I also recommend that you Torque these bolts up - Dry - No Lubrication.
The 100mm Bolt has 43mm of thread - Meaning that this bolt will clamp anything from 53mm to 84mm
