extended studs for Datsun 520 521 620 310 7/16x20 thread only 10 pieces
7/16x20 thread. make sure this is the correct thread size you need before ordering.
These are recommended if your using a wheel spacer or some aftermarket wheels.
These studs have
and longer than stock by about an inch. They are splined the right size~ BUT you WILL have to grind a flat in the head so the stud fully seats in the factory location. This provides a double-locking feature to the stud. Get 1 or 2 extra lugnuts and a handfull (4-6) of flat washers. For the front hubs align the studs so that flat will pull into the factory step on the back of the hub, generously apply white grease, axle grease, etc., (NOT WD-40) to threads, washers, and spare nut. Run nut on UPSIDE DOWN, and torque studs into place. One spare lugnut will do the front, use a fresh one for the rear lest you start damaging stud threads. The rear is a bit trickier! To avoid completely disassembling the park and hydraulic brakes, AND pressing the bearings off then back on the axles~ you'll need to drill or torch a small hole by the lower rearward backing plate bolt to fit the new stud through~ they're too long to angle into position. Then repeat the process as you did on the front. Don't worry about the hole, it will actually let some cooler air in and help your brakes
