This hexagonal bolt has a length of 1/2" with a threading of 1/4-20 [Fully 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 5 increases its strength against the pressure and has a tensile strength and hardness of 120,000 psi | Rockwell C25. Furthermore, it features a shear strength of 72,000 psi.
UNC | Coarse threads are an industry standard. These bolts are classified as IFI 111 | SAE J429 and comply with dimensional standards.
