Hobson UNC Heavy Hex Nut, 7/16"

There are 16 Hobson UNC heavy hex nuts (UNC thread, Grade 2H, plain finish): 5/16" to 3-1/2". A heavy hex nut is a larger, heavier pattern than a standard hex nut. It is turned with a spanner or socket onto a bolt, stud or threaded rod of the same thread form, diameter and pitch.

Gr means the imperial grade-strength level of a screw or nut, for example Grade 2, Grade 5 or Grade 8. The 2H nut is a nut strength level designation (ASTM A194 Grade 2H Heavy Hex Nut). UNC means Unified National Coarse Thread and TPI means threads per inch.

Key specifications

Choosing the right option

Match the nut to the bolt, stud or rod: thread form, diameter and pitch must all agree. Sizes are nominal thread diameters in inches; compare the threads per inch with your bolt. Choose the class or grade to suit the bolt you are fastening, and confirm the pairing with your specification if the joint is load-critical.
