INDEXCold formed fasteners
US aerospace supplier Sussex Wire has
introduced a threaded fastener designed
to improve strength and economy in critical
applications.
The CRES fastener has a threaded shank
with an overall length of only 0.676", and
a low-profile 0.25" diameter oval head. A
reverse hex extrusion on the end of the
shank opposite the head is created by cold
forming and thread rolling. The economy
of cold forming, coupled with the ability to
create the hex socket without collapsing
the reverse extrusion, was achieved through
specialist tool design by the company’s
in-house team.
The component is said to incorporate all
of the benefits of cold forming, including
high part throughput rates, significant cost
economy, and 100 percent net shape,
resulting in zero scrap or material waste.
In addition, the finished part is clean and
burr-free after forming, eliminating expensive
secondary operations.
Sussex Wire says, however, that because
of work hardening via cold forming and
thread rolling, material hardness increases to
130,000 KSI from the original material tensile
of 85,000 KSI, substantially improving integrity
and durability, an important factor in mission
critical applications such as aircraft and
aerospace assemblies.
Sussex Wire utilises cold forming and roll
forming at room temperature to shape
metal wire and alloys into highly engineered,
precision, micro-miniature components.
Wise cable choice
Superior Essex has launched its PowerWise™
category
5e
cable,
a
22-gauge
communications data cable specifically
designed for Internet connected devices
that utilize power-over-Ethernet (PoE) and
require higher levels of current.
The PowerWise cat 5e cable provides 88
percent power efficiency for POE+and future
4PPoE applications over 100m distances.
This improved power efficiency is due to 22
gauge copper wires being 59 percent larger
than the 24-gauge copper wires typically
used in category 5e cables.
While some PoE devices require a cat 6A cable
to support 10GB Ethernet, many devices will
never need a data rate that exceeds the
throughput capability of cat 5e. For devices
such as LED lighting fixtures, the ongoing
cost and the initial cost of the installation are
the most important considerations for POE
cable selection. PowerWise CAT 5e cable
combines the power efficiency benefits
of 22-gauge copper conductors with the
design cost benefit of CAT 5e.
