Product specification
Proven screw retention and good screw sealing in all industries for use with standard screws and nuts.
Vibration- and noise-absorbing
Protection from corrosion and electrolytic effects
Protection of different surfaces including enamels and surface-treated materials
The retaining lips enter the thread pitch of the screw/nut when mounting the washers, thus packing all cavities between workpiece and screw head. The elastic material fits around the head of the screw/nut, ensuring additional screw/nut retention and sealing.
The washers have the best effect with single use and should be tightened with a wrench. In specific mounting cases, a short retightening after approx. 24 h is recommended. Electric and pneumatic screwdrivers can be used without problems.
Partly resistant to diluted chemicals including oils, petrol, benzene, lower alcohols, esters, ketones, ethers, chlorine, hydrocarbons, light alkalis and diluted organic acids.
Technical specification
Material: PA 6 (polyamide 6)
Colour: natural
General Information
Universal washers or spacer rings
Ideal sliding rings between rotating parts
Insulate moisture and electricity
Absorb vibrations
Chemical features:
Resistant to aromatic and aliphatic hydrocarbons, fuels, mineral oils and mineral lubricants; suitable for alkohols, esters, ketones, ethers and amines; good resistance to weak alkalis, but only moderate resistance to strong alkalis; limited resistance to weak mineral and organic acids; not resistant to oxidizing acids, strong mineral and organic acids as well as phenols; limited resistance to hydrolysis
Material specification:
Polyamide is an elastic, tough, loadable, but notch-sensitive material
Impact resistant
Resistant to abrasion and cold
High fatigue strength and excellent resilience
High wear resistance and good mechanical damping capacity
Insulating properties and an amazingly high tensile strength
Connecting parts made of polyamide and similar plastics protect from rust and corrosion damage
Polyamide can also be used in the food processing industry and in medical fields
PA 6 features a higher impact resistance compared to PA 6.6
PA 6 has the highest water absorption of all common plastics up to 9 to 10 % (followed by PA 6.6 with 8 to 9 %), thus considerably increased toughness, flexibility and elongation. However, the strength of the material can therefore be reduced by up to 10 %.
