  • Featuring a six-sided hexagon socket and constructed from highly durable alloy steel material, National Bolt & Nut's button head hex socket cap screws possess a larger surface bearing and a lower profile head than traditional socket cap screw heads. Button head hex socket cap screws are often employed in applications where the material is too thin to countersink.
  • Meeting ANSI B18.3 dimensional specifications, our coarse threaded button head hex socket cap screws are available in a variety of different lengths and thread sizes to accommodate our clients unique application requirements.
  • Other materials and finishes available. For further information, call or send an information request.
