Imperial Plow Bolt Partial Thread Plain Alloy Steel 1-8 * 4-1/2" Grade 8 unf These bolts are classified as

These bolts are classified as ASME B19

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

An irregularlyshaped thread at the top of the nut grips the bolt for a stronger hold than nylon-insert locknuts

A Yellow Zinc-plated steel provides corrosion resistance in wet environments and adds lubricity so they thread on smoothly

This hexagonal bolt has a length of 9 with a threading of 1-1/2-6 [Partially Threaded]

Imperial Plow Bolt Partial Thread Plain Alloy Steel 1-8 * 4-1/2" Grade 8 unf These bolts are classified asThis plow bolt has a length of 4 1 2" with a threading of 1 8 [Partially Threaded]. It is made of plain alloy steel and thus provides low resistance to corrosion in dry and wet environments. 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
