Black Stainless Fasteners have an attractive matte black finish and are abrasion resistant.
The finish does not peel, chip or rub off and does not change the strength of the stainless steel.
This specialty secondary process also reduces friction, prevents galling. There is practically no dimensional change to base fastener.
Double ended studs, or "tap end studs" have a shorter length of thread on one side, an unthreaded middle shank, and a longer length of thread at the other end. Both sides are right hand threaded and can accept a nut or installation into a tapped hole.
