    ### 1/4 inch Hex Nut UNF 304 Grade Stainless Steel Pack 100

Match a 1/4 inch UNF thread with this hex nut in 304 grade stainless steel. The size and thread series identify the variant to compare with your bolt, screw or threaded rod.

The six-sided form provides flats for a suitable spanner or socket. Check tool clearance around the assembled joint and confirm that the thread matches before tightening.

This code is the 1/4 inch UNF option. UNF is the stated thread series, so confirm the mating fastener uses UNF rather than UNC.

Supplied in a pack of 100, this bulk option is useful when you need repeated matching fasteners or want to organise a supply of this exact size. Check the full pack quantity when comparing it with smaller prepacked versions.

Check the required grade and any application-specific fastening specification before ordering. The material grade is not a substitute for a published mechanical strength class or load rating.

### Choosing and using this product

Plan tool access with the surrounding equipment in place. There may be adequate room to insert a fastener but limited space to hold the opposite end or operate the required tool. Checking both sides first helps make the installation practical to assemble and inspect.

Consider future inspection as part of the fitting layout. The fastener and surrounding surface should remain accessible wherever practical, particularly on components that are removed for service. Follow the equipment guidance for tightening and any required locking method; neither is established by the pack size.

For repeated workshop jobs, keep unused stock in its labelled packaging. Recording the thread, length, head style and material together makes the next matching purchase easier and reduces the chance of substituting a superficially similar piece from another pack.
