ISO14579 Hexalobular Socket Head Cap Screws
| Applications/ Advantages |
Ideal for precision assembly work wih close tolerances and applcations needing a welltooled appearance.Supples greatertensile strength than equivalent sizes of Grade-5 or Grade-8 hex head cap screws while requiring less surface area or counterbore since the fastener is internally wrenched. |
| 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 he following elements shall e present in sufficient quantity to meet the strength requirements listed below:chromium,nickel,molybdenum or vanadium. |
| Heat Treatment | Cap screws shall be heat reated by oilquenching from abovethe tansformation temperature and then tempered at atemperature not ower than 650°F. |
| Hardness | 0 through 12”diameters:Rockwell C39 minimum;5/8”diameter &larger:Rockwell C37 minimum |
| Cap screws of alength 3D or greater,where Dequals the noninal diameter of hescrew are subjecto tensie stengt, yield stength, elongaion and reoucion ofarea esing | |
| Tensile Strength | 0 through 1/2”diameters:180,000 psi.minimum;5/8”diameter &larger:170,000 psi.minimum |
| Yield Strength | 0 through 1/2”diameters:162,000 psi.minimum;5/8”diameter &larger:153,000 psi.minimum |
| Elongation | 10%minimum (applies to machined specimensof length at least 4D where D equals the nominal diameterof the screw) |
| Reduction of Area |
33%minimum(applies to machined specimens) |
