Westfield Fasteners Product Specification:

DIN 934 - Full Hex Nuts (Standard Pitch)

This product guide contains the specification for metric threaded full hex nuts available from Westfield Fasteners. The basis of this specification is the DIN standard DIN 934.

Product Description
Hexagon full nut to DIN 934 (similar to ISO 4032), with standard metric coarse pitch. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assemblies throughout the world. Can be used in conjunction with hexagon thin nuts in a "locking" formation for a more secure fitment.
Scope of the DIN Standard.
DIN 934 specifies the tolerances and the variation in form of metric threaded full sized hexagon nuts, for sizes from M1 up to and including M160. Fine pitch and left hand thread variants are also covered under this standard.

Table 1 below defines the overall dimensions and tolerances of this nut type.

Although the DIN 934 standard has now been superceded by ISO 4032, off the shelf parts are currently more generally available to the older specification. The ISO standard specifies revised nut heights and across the flats dimensions on certain sizes, but are otherwise interchangable.

Variations from DIN 934
DIN 934 covers materials including carbon steel, and A2 & A4 stainless steel. The hex nuts we stock in other materials and grades are made with reference to this standard, but are not mentioned specifically. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" this specification and the DIN 934 standard upon which it is based.
