Available types:
--Without cap
--Plastic cap: Technopolymer plastic, DELRIN®, white (natural color)
--Plastic cap, electrically conductive, surface resistivity < 106Ω, volume resistivity < 107Ω
--Rubber cap: Thermoplastic TPE rubber, 73 Shore hardness, black
--Rubber cap, electrically conductive, surface resistivity < 106Ω, volume resistivity < 107Ω
Hex nut: Steel, zinc plated, blue passivated, ISO 4032

GN 343.1 leveling mounts can bear high static loads, but for high loads, they should be used in conjunction with screws of high tensile strength. Recommended are DIN 915 dog point socket set screws, available upon request. The dog point must be seated squarely at the bottom of the threaded hole, which will increase the load capacity of the ball in the socket.
Tensile strength of steel in base: 500 N/mm2.
Mounts are supplied assembled.
*Load values in table valid only for without cap and with plastic cap types.
