inox.ie Catalogue > Bolts & Machine Screws > Machine Screw - Button Head, Hex Socket - IMPERIAL THREAD

Stainless Steel Hexagon Socket Button Head Screws with Imperial UNC & UNF Threads

Stainless Steel Hexagon Socket Button Head Screws with Imperial UNC & UNF Threads

Stainless Steel Button Head Machine Screws are fully threaded with Hexagon Socket, similar to ISO 7380


Most of our stock is in A2 / 304, with a few items in A4 /316 Stainless Steel.

There are a variety of different standards for Imperial threaded items. The most commonly availabe are based on the American Unified Thread Standard (UTS). There are both Coarse (UNC) and Fine (UNF) thread types available, with UNC the most comonly used.

When specifying the diameter of a UNC or UNF Bolt, it is common practice to specify the threads per inch (tpi) after the diameter. For example 1/4-20 x 1" has a 1/4"diameter with 20 tpi (UNC) and is 1" long.

You may download a table on Metric and Imperial Threads here:

We hold only a limited stock of Imperial Threaded UNC & UNF items. Please contact us, if you require large quantities or other sizes.
