G10/FR4 A phenolic laminate, which can be fabricated to tight tolerances for medical and aerospace production parts. G10/FR4 material has superior mechanical properties, particularly it’s extremely high strength and high dimensional stability over temperature which allows it to hold details of threads and thin features for demanding insulation applications. G10/FR4 offers excellent chemical resistance and electrical properties under dry and humid conditions. G10/FR4 features high flexural, impact, superior mechanical strength and bond strength at temperatures up to 285°F.

Galling Wear produced when two metallic pieces rub against each other. High points on each surface will gouge in to the other. This then creates more friction between the surfaces.

Gap The distance between two components.

Gasket A piece of material like rubber or foam that surrounds a hole so that when compressed it prevents air, water or dust from going in.

Grip The nominal total panel thickness for which a fastener is to be used.

Grip Length The effective length in terms of screw thread engagement, screw length, stud length, rivet shank length, etc., that will accommodate a defined panel thickness range and provide for effective latching or panel retention.

Halar © Ethylene-Chlorotrifluorethylene copolymer exhibits better mechanical properties than many other fluoroplastics. But like other fluoroplastics, its flame retardance, chemical resistance and low dielectric constant remain constant over a wide temperature range. These qualities make it suitable for use in such products as electrical insulation, monofilament, tank linings, housings, and electrical components. It may be usefully employed at temperatures from the cryogenic range to about 330ºF.
