On speed riveting tools such as the 0727 type, the nose equipment always consists of three elements; a nose jaw, a mandrel and a
follower spring. All three items are matched to the fastener being placed and to the hole size in the application.
To avoid complete dismantling of the tool it is essential to check the orientation of the cursor before fitting the
It is essential that the correct nose equipment is fitted to the tool to ensure both effective placing of the fastener
and SAFE operation of the tool. READ THE SAFETY INSTRUCTIONS pages 2 and 3 carefully.
To identify the correct combination of nose equipment to fit your tool first select a nose jaw by reading the section below then read the
mandrel section to select part numbers both for the mandrel itself and for the mandrel follower spring. Mandrels and mandrel follower
springs are illustrated on page 9.
To fit the nose equipment, follow the 'Loading the tool' procedure on page 8.

The wrong nose jaw could result in an incorrectly placed fastener or unsatisfactory clench.
Nose Jaws can be categorised into seven different basic shapes as drawn opposite, even though internal dimensions will vary according
to the fastener it is intended for. Exact dimensions referring to the letters in the illustrations opposite are indicated in the 'NOSE JAW
SELECTION TABLES' over the next two pages.
For a particular shape, there may be several options of end form giving access benefits or fastener placing enhancement.
FLAT
■
Normal end form of all nose jaws.
■
Suitable on all applications with no access restrictions.
UNIVERSAL
■
Designed for use with universal head Chobert fasteners.
■
Can also be used with Briv fasteners to obtain the highest possible clench. Note this reduces the maximum grip range of the Briv
fastener by approximately 0.015" (0.4mm).
RECESSED
■
For use with Briv fasteners ONLY.
■
It gives a higher clench than a flat end form but less than a universal end form, with no reduction of the grip range of the fastener.
TAPERED
■
Available as shown in the 'Nose Jaw Selection Tables'.
■
Allows greater accessability than a flat end form and places the same range.
HEAD FORMING
■
For use with Rivscrew fasteners ONLY.
■
Deforms the heads of the fasteners to achieve good clench.
