The Grade 5 increases its strength against the pressure and has a tensile strength and hardness of 120
The stud or bolt you use will affect the overall Working Load Limit
It is made of black zinc plated and thus provide medium resistance to corrosion in dry environments and low resistance in wet environments
This hexagonal bolt has a length of 8" with a threading of 1-1/8-7 [Partially Threaded]
provides high resistance to corrosion in dry and wet environments
Socket Head Cap Screw Fine Thread Black Steel 3/4-16 * 4" Grade 8 [Cup Point] [Allen Drive] bolt The Grade 5 increases itsWith 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 3 4 16. 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.
