Sharq P300TM gravel grader blade

For gravel road maintenance nothing rivals the Sharq P300 which easily cuts even the hardest compacted gravel and extends grader blade life by up to 200 per cent.

As opposed to thicker blades which require more power to operate effectively; the Sharq P300 Grader Blade cuts easily, crushes less gravel and runs smoothly, saving you time, money, increasing cab comfort, and decreasing the need to add new gravel to the road surface.

Plow bolts and nuts

Whenever you are replacing grader blades, plow bolts should also be replaced to minimise the chance of future unplanned downtime or replacement issues.

All Cutting Edges plow bolts are cold forged and undergo a carefully controlled heat treatment process to ensure a minimum tensile strength of 170,000 psi 14% greater than SAE Grade 8) and a core hardness of Rockwell C36-42.

Further strength is delivered in the fully formed square neck and a raised spherical formed head. Grade 9 plow bolts with a raised countersunk head are also available.

All UNC-2A threads have radiused root run-out and blend smoothly into the shank to give added fatigue protection.
