The screw has a length of 3" and a thread of 1-8

This hexagonal bolt has a length of 4-1/2 with a threading of 7/8-9 [Partially Threaded]

This hexagonal bolt has a length of 8 with a threading of 1-1/4-7 [Partially Threaded]

The Grade 5 increases its strength against the pressure and has a tensile strength and hardness of 120

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

Socket Head Cap Screw Full Thread Black Steel 9/16-12 * 3-1/2" Grade 8 [Cup Point] [Allen Drive] thread_size_1-2-13 The screw has a lengthWith 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 3 1 2" and a thread of 9 16 12. Black oxide steel screws are mildly corrosion resistant in dry environments. Coarse threads are the industry standard: choose these screws if you dont know the pitch or threads per inch. Screws that meet ASTM A574, ASTM A574M, and ISO 898 1 comply with
