Socket Head Cap Screw Fine Thread Black Steel 1-1/8-12 * 4" Grade 8 [Cup Point] [Allen Drive] length_1

Socket Head Cap Screw Fine Thread Black Steel 1-1/8-12 * 4" Grade 8 [Cup Point] [Allen Drive] length_1With 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 4 and a thread of 1 1 8 12. 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 Grade 5 increases its strength against the pressure and has a tensile strength and hardness of 120

The screw has a length of 3/4" and a thread of 5/8-11

It is made of zinc plated and thus provide medium resistance to corrosion in both dry and wet environments
