Alloy Steel Thread-Locking Socket Head Screws, JX-22JG518-M14-16-ST

Alloy Steel Thread-Locking Socket Head Screws, With a tensile strength of 170, 000 psi, these alloy steel screws are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. Their black-oxide finish provides mild corrosion resistance in dry environments. A nylon patch bonded to the threads adds friction to resist loosening from vibration. Screws are reusable, but their holding power lessens with each use. Length is measured from under the head.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads. Screws that meet ASTM A574 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.3 and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

Alloy Steel Socket Head Screws

With a tensile strength of 170, 000 psi, these alloy steel screws are stronger than Grade 8 steel screws. 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. The screws with a blue-dyed finish are easy to distinguish. Zinc-flake-coated steel screws are 20 times as corrosion-resistant as zinc-plated screws and comparable to Dacromet-coated screws. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance. They are not compatible with coarse threads. Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.3, ASME B18.3.1M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
