Thermoplastic
Material: Nylon 6 + Polypropylene (PP)
Working temperatures: Nylon up to 130°C peak and 80°C continuous use. Polypropylene maximium 70°C.
Resistant to: alcohols, esters, aromatic hydrocarbons, dilute alkalis, ketones, oils, fuels, grease, fats, weatherability (including UV light – excludes coloured Nylon) and salt water.
With PP also avoid halogenated hydrocarbons and flammable materials (can hold static charge).
Reinforced Thermoplastic
Material: Nylon 6 glass filled
Working temperature: up to 180°C peak, 110°C continuous use.
Resistant to: alcohols, esters, aromatic hydrocarbons, dilute alkalis, ketones, oils, fuels, grease, fats, weatherability (including UV light) and salt water.
Duroplast
Material: Phenolic Based Duroplast (PF)
Working temperature: -30°C to 160°C
Resistant to: diluted mineral acids, alcohols, chlorinated hydrocarbons, aromatic hydrocarbons, detergents, grease, oils, weatherability (including UV light). Avoid high pressure or high impact loads (can shatter).
Soft-Touch Mouldings
Material: Polypropylene substrate, TPE over-mould. Rencol has standard parts already available in this design, used particularly extensively in both industrial and special needs market products.
Brass
Material: BS2874 CZ121. Especially recommended for any materials likely to have continued exposure to temperatures below -30°C, where most steel grades become brittle. Also used as a marine grade material when nickel plated.
Zinc Plated Steel
Material: EN1A leaded-bright zinc passivated.
Stainless Steel
Material: Standard grade is 304. For medical, catering or marine use recommended grade is 316 – has high chloride resistance.
Aluminium
Grades are 6061 and A380. Others available on request.
Colours
Colour options include black, red, yellow, green, blue, white and grey. Other colours are available on request. If you would like to see the colours before ordering, samples can be provided free of charge.
Thread Depths
Wherever possible thread depths are a minimum of 1.5 x the diameter of the thread.
Tolerances
In general, our products are produced to the following tolerances:
Bore sizes: ± 0.1mm
Outside dimensions: ± 2mm
Bridge handle centres: ± 2mm
Male thread length: ± 1mm
Tightening Torque
All tightening torques are to Standard 0.5T, which assumes a metal screw fixed into a non-metallic substrate. If the mode of employment is metal to metal assume the tightening force should be double this value.
Mounting Hardware
Screw shear values are calculated on the basis of the largest metric screw which will fit the bore.
Load Values
Axial loads are parallel to the hinge pin. Radial loads are perpendicular to it.
All values are approximate and for guidance only.
