Steel Wire-Lockable Hex Head Screws
Fully Threaded
Partially Threaded
These Grade 5 steel screws are over 70% stronger than our stainless steel wire-lockable hex head screws. Wire these screws together through the hole in the head to get more vibration resistance than any other screw (wire sold separately). Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.2.1 specifications. Grade 5 steel hex head screws are marked with three radial lines. Length is measured from under the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments.
Zinc-plated steel screws resist corrosion in wet environments.

Vented Hex Head Screws
Fully Threaded
Partially Threaded
Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications. Screws are 18-8 stainless steel, which has good chemical resistance and may be mildly magnetic. Length is measured from under the head.
