Nylon fasteners offer excellent insulation in electrical and electronic applications.

Nylon fasteners are lightweight and resistant to vibration and abrasions.

Nylon fasteners are nonmagnetic and resist most solvents, petroleum oils and greases.

PEEK fasteners (chemically known as Polyetheretherketone) offer a unique combination of properties for some of the most extreme applications.

PEEK is classified as semicrystalline thermoplastic and high purity polymer, offering excellent mechanical strength and chemical resistance at high temperatures.

PEEK fasteners offer a high strength alternative to PTFE fluoropolymers.

PTFE screws are made from the fluoropolymer polytetrafluoroethylene and are known for being exceptionally corrosion resistant and inert at elevated temperatures.

PTFE screws are inert to most chemical environments including organics, acids, bases, mixed chemicals and hyrdofluoric acid.

Additionally PTFE screws are bio-inert and will not leach into or contaminate sensitive pharmaceuticals or food based products.

Compared to other high performance polymer screws like PEEK or PVDF, PTFE screws offer the best all-around corrosion resistance especially at elevated temperatures. However the trade-off for its extraordinary corrosion resistance is the lower tensile strength compared to PVDF or PEEK screws.
