Unbrako Low Socket Head Cap Screws are high strength, precision fasteners designed for applications where head height clearance is a problem, thus it is suitable for use in parts too thin for standard Socket Head Cap Screws. Low Socket Head Cap Screws cannot be pre-loaded as high as a socket head cap screw because of their reduced head height and smaller socket size.

  • Low head height make these ideal for use in applications with limited clearance or parts too thin for standard socket head cap screws.
  • Specially designed elliptical fillet doubles the fatigue life at critical head-shank juncture.
  • Smooth, burr-free sockets, uniformly concentric and usable to full depth for correct wrench engagement.
