Wire-Lockable Rounded Head Screws
Wire these screws together through the hole in the head for better vibration resistance than any other rounded head screw. They have fillister head with a deep drive to maximize driving power and a narrow diameter to fit in tight spaces. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. All are passivated to Fed. Spec. QQ-P-35 for added protection against oxidation and corrosion. Length is measured from under the head.

Stainless Steel Wire-Lockable Socket Head Screws
Fully Threaded
Partially Threaded
Screws are 18-8 stainless steel for good chemical resistance. They may be mildly magnetic. For more vibration resistance than any other socket head screw, wire these screws together through the hole in the head (wire sold separately). All screws meet ASME B18.3 and ASTM F837 for dimensional standards and material quality. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Alloy Steel Wire-Lockable Socket Head Screws
Fully Threaded
Partially Threaded
Screws are alloy steel with a tensile strength of 170,000 psi, making them stronger than Grade 8 steel screws and more than twice as strong as stainless steel wire-lockable screws. Their black-oxide finish provides mild corrosion resistance in dry environments. For more vibration resistance than any other socket head screw, wire these screws together through the hole in the head (wire sold separately). Dimensions meet ASME B18.3 specifications. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

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.
