Socket Head Cap Screw Black Steel 1-8 * 5-1/2" Grade 8 [Cup Point] [Allen Drive] carriageWith 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 screws have a thread of 1 8 and a length of 5 1 2. 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
This hexagonal bolt has a length of 2" with a threading of 1-8 [Fully Threaded]
This hexagonal bolt has a length of 3-1/2" with a threading of 1-1/4-7 [Fully Threaded]
This hexagonal nut fit a threading of 7/8-14
This hexagonal bolt has a length of 6" with a threading of 1-1/8-7 [Partially Threaded]
The screws have a thread of 3/4-10 and a length of 11
The Grade 8 increases its strength against the pressure and has a tensile strength and hardness of 150
The screws have a thread of 1-3/4-5 and a length of 15
This hexagonal bolt has a length of 4" with a threading of 5/8-11 [Partially Threaded]
This hexagonal bolt has a length of 2-1/2" with a threading of 1-1/4-7 [Fully Threaded]
This hexagonal bolt has a length of 7" with a threading of 5/8-11 [Partially Threaded]
This hexagonal bolt has a length of 6" with a threading of 1-3/8-6 [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
