PIC Design offers an extensive line of precision Hardware which
contains various items for fastening and/or locating of precision
industrial components. The hardware is manufactured from Stainless
Steel to the PIC high quality standards, in either inch or metric styles of
thread, diameter and length.
The following pages have been included as a technical guide to aid the
designer or engineer in selecting the appropriate screw type and size.
The drill and tap data in inch for both the UNF and the UNC pieces,
selects the correct drill to be used for the appropiate tap. For the metric
ISO thread, the correct drill is recommended for the thread size and
pitch.
The screw head detail data for both inch and metric heads enables the
designer to select the appropriate type of head required and to allow for
the clearance of the heads.
