10/24 X 3/4 Low Head Alloy Steel Socket Cap Screws
Product Detailed Description
10/24 X 3/4 Low Head Alloy Steel Socket Cap Screws
- Description: Similar to a standard alloy socket cap screw except the head height is 50% of the standard's and the socket size is smaller.
- Applications/Advantages: Used in applications where the limited clearance would not accomodate the head height of a standard socket cap screw. Also used in counterbored holes of material too thin for a regular socket cap screw. However, because of their design, they cannot withstand the same preloads as a standard socket head.
- Material: Cap screws shall be made from an alloy steel which conforms to the following chemical composition requirements (per product analysis)-- Carbon: 0.31% minimum; Phosphorus: 0.040% maximum; Sulfur: 0.045% maximum. Also, one or more of the following elements shall be present in sufficient quantity to meet the performance requirements listed below: chromium, nickel, molybdenum or vanadium.
- Heat Treatment: Cap screws shall be heat treated by oil quenching from above the transformation temperature and then tempered at a temperature not lower than 650 °F.
- Hardness: Rockwell C38 minimum
- Tensile Strength: 170,000 psi. minimum
- Yield Strength: 150,000 psi. minimum
- Elongation: 10% minimum (applies to machined specimens of length at least 4D where D equals the nominal diameter of the screw.
- Reduction of Area: 33% minimum (applies to machined specimens)
