Customer Reviews (5.0 / 5 · 5 reviews)

Evelyn ★★★★★

Had to replace some bolts on a heavy-duty agricultural implement, and these L9 alloy screws handled the torque perfectly. The yellow zinc coating seems to resist corrosion already, and the threads were clean and sharp right out of the package.

Daniel ★★★★★

Needed a set of strong bolts for a press jig, and these L9 alloy steel heads took the torque without any deformation. The yellow zinc coating looks good and seems like it'll resist rust in the shop.

Chloe ★★★★★

Bought these for a gearbox rebuild and the L9 alloy steel took the torque wrench without a hint of stripping. The fully threaded length made alignment a breeze, and the yellow zinc finish looks clean and uniform. Pack of 50 means I've got spares for the next job.
