DA-4600 Product Picture

With a quarter turn stud rotation; the DA-4600 Line studs engage sloped cams in the receptacle and lock into a dead-end detent. Cam action pulls the bottom of the receptacle up against spring tension. Arrival at the locked position is obvious due to an over-rotation stop and a detent snap action that can be felt.

Manufactured from lightweight, high strength thermoplastics, the DA-4600 Line quarter turn fasteners provide a modern, stylish finish coupled with the advantages of quick access and low installed cost.

The fasteners lock with a vibration-resistant clamping tension, cannot be overturned, and may be operated thousands of times.

Installation is fast and secure. Studs may be held with push-on retainers or pushed through molded one-way holes. Receptacles may be riveted or snapped into rectangular holes from above or behind.

The evident quality experienced with DA-4600 Line fastener operation will reflect well on the products which use them.

Selection Procedure

  • Select a head style.
  • Select a retainer.
    Retainers captivate a stud to a panel and, unless they are absorbed into the panel or support, add thickness to the Total Material Thickness. A special self-retaining hole is possible if your material is a ductile plastic
  • Determine the receptacle size and stud grip length.
    The stud grip length or G depends on the type of receptacle chosen and the thickness of your materials. Use the tables provided with each receptacle to determine the proper receptacle size and stud length needed for your application. Standard stud lengths range from 0.45"  to 1.00" (11.43 to 25.40 mm).
Panel Thickness
The thickness of the material that contains the stud.
Support Thickness
The thickness of the material where the receptacle will be mounted.
Gap Thickness
The thickness of anything that will prevent the panel from coming in direct contact with the support. This will possible include rivet head thickness and / or stud retainer thickness

Self Ejecting Feature

Note: The Self Ejecting Cup adds .090" (2.29 mm) to the Total Material Thickness or Panel Gap Thickness. A minimum panel thickness of .040" (1.02 mm) is required for the Self Ejecting Feature.

Note: For the Self-Ejecting feature, specify "SE" between the stud "G" Dimension and the color. For example: a 4604-50-BK would become 4604-50-SE-BK.

Material:
Cup: Black acetal resin
