Flat-Plate Drive Pipe Connector Kit

The Flat-Plate Drive Pipe Connector Kit features a 1/2 in. x 4 in. zinc-plated grade 5 hex head bolt and a 1/2 in. nylok nut. 16 thread count bolt. 13 thread count nut.

Grade 5 heavy hex bolts externally threaded fasteners made of carbon steel.  Bolts designated as heavy hex bolts are very similar to standard hex bolts however the head size across the flats and across the corners is larger providing a broader bearing surface.

Grade 5, identified by three radial lines on the head, designates the mechanical properties of a fastener.  Medium carbon/carbon steel with additives. They are quenched and tempered for added strength.  Grade 5 fasteners are higher in tensile and yield strength and have proof load and hardness ratings higher than Grade 2 fasteners.

Includes:

1/2 in. x 4 in. zinc-plated GR5 hex head bolt
1/2 in. Nylok nut
