Craftech adds a Leveling Foot to expanding product line. Leveling foot provides shock, vibration and noise reduction and simplified leveling for machinery, racks, assembly lines and other equipment such as semiconductor wet bench applications. This 1/2-13 (12mm x 1.75) self-leveling foot with stainless steel swiveling screw is available in Polypropylene and Flame Retardant Polypropylene, in a variety of colors.
The 316 stainless steel screw is offered in three |

| New Tooling for Metric Screws | ||
| The mold making
department has built a new series of precision molds for metric (DIN) size screws: M3, M4, M5, M6, in lengths 6mm to 25mm. Head styles available: slotted pan, cheese, flat as well as hex head machine screws. Available materials: Glass-filled Nylon and Glass-filled Flame Retardant Nylon, Isoplast™, PEEK®, Ultem® 2300, Glass-filled PPS, Glass-filled Lexan, Glass-filled Noryl® and Glass-filled Polypropylene. |
 Samples available on request. |

RADEL
Radel® resins provide exceptional hydrolytic stability, and toughness
that is superior to other commercially available, high temperature engineering resins.
Radel resins also offer high deflection temperatures, excellent thermal stability, good
electrical properties and outstanding resistance to environmental stress cracking. The
polymer is inherently flame retardant meeting stringent industry flammability requirements
for aircraft interiors. It also withstands repeated steam sterilization and harsh boiler
additive chemicals in medical applications. Compared to Ultem®, the Radel R series' izod
notch is considered 10 times better, chemical resistance twice as good and autoclaving,
substantially better. |
