Press-fit threaded standoff bushings – blind thread – Application The hexagon is pressed flush into round mounting holes. Clifa®-ABG is a press-fit threaded bushing with blind tapped hole (sealed thread) for the production of wearresistant, heavyduty screwconnections in thinwalled moulded parts from thickness 1,0 mm. Article number of the first group of digits Internal thread Article number of the first group of digits for sheet metal thickness External diameter Hole diameter Minimum spacing from 1,0 from 1,0 from 1,3 from 1,3 Internal thread Bushing length ... ... 030 ... ... 1.. 030 ... ... ... 040 ... ... ... 050 ... Thread length C Example for finding the article number Press-fit threaded bushing Clifa®-ABG with internal thread M4, bushing length 10, made of hardened, zinc plated, blue passivated steel for metal sheet thicknesses from 1,3 mm: Clifa®-ABG 571 010 040.110 Bushing length B available from 8,0 to 25 mm in intervals of 1,0 mm. The fourth digit of the article number is used to differentiate the across-flats SW measurement for the thread dimension M3, the fifth and sixth digit to identify the bushing length B (571 003…; 571 004…; 571 005…; 571 …). Steel hardened, zinc plated, blue passivated Article no. (fourth group of digits) … … … 110 Other finishes or special shapes on request. Tolerances Press-in force as a guideline value for selection of the press Clifa® ABG Press-in force The required press-in force must be determined by trial and error. For different material qualities and surfaces, higher press-in force may be required. The firmest fit is achieved if the recommended hole diameters and tolerances are precisely adhered to.
