Rino stays tight with
Staytite nuts
Rino Industries Ltd of Chesterfield, UK, has
announced the launch of a new range of high
quality nuts into its newest 848 page mail
order catalogue.
Every Staytite nut, regardless of nut body
material, is assembled with a stainless steel
spring insert. This ensures that its abilities do not
suffer from corrosion, explains Rino. As the nut is
installed on the screw thread, the stainless steel spring
insert engages with the base of the screw thread and flexes upward. The
advantage this gives is a lower installation torque when compared to other
types of self-locking nut, particularly those of the deformed thread type.”
During use, Rino says the Staytite nut resists vibration and loosening
because the inserts flex downwards and are actually ‘pulled’ into close
contact with the screw threads by the upwards anti-clockwise rotation of the
nut body. This also produces a very effective interference fit between the
threads of the nut and screw. Staytite therefore have a low installation and
seating torque, but a high removal torque.
“A spring steel insert will revert to close to its original
shape far better than a deformed or de-pitched nut
made from non spring steel material. This means
that on the second and subsequent installations it
can out perform many other types of self-locking
nut.”
Staytite nuts are available in mild steel, high
carbon, 304 and 316 stainless steels and other materi-
als on request.
Ball Lock™ Mounting System
speeds accurate locating
Jergens, Inc. says that its patented Ball Lock™ Mounting System is the
practical quick-change system for fixing into metalworking and metal-
forming operations, for either horizontal or vertical machining centres.
“With the current trend toward smaller production runs, the ability to set
up quickly for the next run is critical to maintaining profitability.”
Jergens’ Ball Lock™ Mounting System speeds accurate locating and locking
of fixture plates to subplates, freeing valuable machine time by providing
quick-change capability. Employing the system generally takes only minutes
and requires only a couple of turns of a set screw, versus the conventional
method of dowel pins and cap screws that might need up to ten turns to
lock.
Repeatability is ±.0005 inch, which minimises or eliminates the need to
indicate fixture position. The Ball Lock™ System securely holds plates together
with working loads up to 20,000 lbs, achieving its holding force by a
combination of force
generators. A threaded
screw exerts force onto a
centre ball, which, in turn,
directs this force onto
three balls that register on
