Presented on this page is our current range of brass bolts and machine screws, to be used in conjunction
with the equivalent brass metric sized nuts and washers available elsewhere on the website. Westfield Fasteners carries stock of each size
and type in our warehouse, ready for immediate despatch. Locking type washers in bronze are available and typically employed for use with brass bolts.
Commonly referred to as a setscrew or simply as a bolt. The fully threaded DIN 933 or ISO 4017 should
not be confused with its DIN 931 equivalent. A standard spanner or ratchet is typically used to fit this
product. Used for decades on all types of assembly throughout the world. As with the DIN 931 hex bolt,
the hex drive allows a higher torque to be applied. All parts are to DIN 933 except where shown otherwise.
The alternative standard ISO 4017 specifies differences in head dimensions for M10, M12 and M14 thread
diameters from DIN 933. Please note that due to manufacturing limitations, all nylon variants of these
items are only "similar to" and not "in absolute accordance with" the standard specified.

Generally used in timber to timber and timber to metal construction, these bolts incorporate a square
neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess
to be included on top of the head. Supplied to DIN 603. Please note that thread lengths stated are a
minimum; In some cases a full thread will be supplied where a partial threaded shank is indicated in
the specification. Nuts are supplied seperately, unlike the mild steel versions available elsewhere on
the site.
