  6. 6. Hex Head Cap Screws vs. Hex Bolts A cap screw has a flat washer face underneath the head Washer Face • Hex bolts do not Cap screws are chamfered on the end easing its insertion into a tapped hole. Tightening • Hex bolts require a nut Cap screws fall under ASTM J429Specs • Hex bolts fall under ASTM A307 Cap screws have tighter tolerances than Hex bolts Tolerances
  7. 7. What is on a Buyer’s Mind?  What Grade is Required?  Hex cap screws come in 3 grades based on strength.  What finish do they need?  It is important to know whether the end user needs them plain or plated  Domestic or Imported?  Some applications require domestic material, while others do not. Whether domestic or import, all hex caps fall under the same specifications and are made under IFI standards.  Is it inch or metric?  Knowing whether the need is inch or metric is critical to servicing the buyer’s needs.

  15. 15. Diameter and Thread Comparison Course and Fine Threaded Fasteners The thread length is the number of threads per inch. So for ¼-20, you have a 1/4’ diameter fastener with 20 threads per inch. Course threaded fasteners have fewer threads per inch than fine threaded products.

  16. 16. Tensile Strength Comparison Tensile strength is the maximum stress level that a fastener can withstand before it exhibits structural loss. That is to say the maximum amount of pressure a fastener can be pulled before it breaks.
