*IMPORTANT. Length of thread is indicative only and can vary between manufacturers within normal practice. It is not necessary to
have a long thread length because of the thread length that is required to be made - in recent years shorter thread lengths are being
recommended increasingly, especially when for machine operations. ISO R.529 sets a maximum threaded length, but not a minimum.

Taps may be supplied with coatings such as TiN (Titanium nitride) to special order, the quantity ordered determining the unit price.

Taps to special tolerance classes (i.e. other than 2B) may be supplied to special order, the quantity determining the unit price.
oversize taps (for making threads which are to be subsequently plated, or for insert repair) may also be ordered, and are
subject to quantity scales as above. Please be sure to specify the exact oversize required, or the insert repair system used.

Sets of Taps
A set of three hand taps in this series will consist of taps with taper, second, and bottoming leads. They are full form, and so
differ only in the length of the chamfered lead provided, so it may not always be necessary to use a full sequence of three taps to
make the finished thread [compare this with serial form taps -shown here (in metric size) under DIN352. Unified serial form taps
may be supplied, but only to special order].

# Unified number sizes. Nominal “inch” sizes for unified screw threads below 1/4” major diameter are no longer recognised — since the
introduction of the unified system in 1949. The major diameter in inches of the number sizes now used is given for reference below.
Requests for UNC or UNF diameters below 1/4” , but expressed as inches (which have never officially existed) may occasionally still be met.
“1/8” UNC and UNF can be supplied as #5, but other diameters have no exact equivalent and would be completely special.
