Imperial Hexagonal Bolt Partial Thread Yellow Zinc Plated 9/16-12 * 3-1/2" Grade 8

This hexagonal bolt has a length of 3-1/2 with a threading of 9/16-12 [Partially Threaded]. It is made of yellow zinc plated and thus provide medium resistance to corrosion in dry environments and low resistance in wet environments, but Yellow Zinc provide a higher corrosion resistance than regular zinc.

The Grade 8 increases its strength against the pressure and has a tensile strength and hardness of 150,000 psi | Rockwell C33. Furthermore, it features a shear strength of 90,000 psi.

UNC | Coarse threads are an industry standard. These bolts are classified as ASME B19.2.1 | SAE J429 and comply with dimensional standards.
