Cold 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.
