Socket Head Cap Screw Fine Thread Black Steel 1/2-20 * 7" Grade 8 [Cup Point] [Allen Drive] Quantity:Unity

Socket Head Cap Screw Fine Thread Black Steel 1/2-20 * 7" Grade 8 [Cup Point] [Allen Drive] Quantity:UnityWith 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. The screw has a length of 7 and a thread of 1 2 20. Alloy steel screws are mildly corrosion resistant in dry environments. 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.

The screw has a length of 5-1/2 and a thread of 10-32

The rod measures 36" and has a 1-8 thread

The screws have a thread of 5/8-11 and a length of 10

The screws have a thread of 1-3/4-5 and a length of 6

Yellow Zinc-plated steel screws resist corrosion in wet environments

This hexagonal bolt has a length of 4-1/2" with a threading of 1-1/4-12 [Partially Threaded]

This hexagonal bolt has a length of 10 with a threading of 1-8 [Partially Threaded]

It is made of cadium plated and thus provide high resistance to corrosion in dry environments as well as medium corrosion resistance in wet environments

but their holding power lessens with each use

ASTM A574M

This hexagonal bolt has a length of 2-1/2" with a threading of 1/2-20 [Partially Threaded]

Also known as nut eyebolts
