Save Space, Weight, and Material
Holo-Krome socket head cap screws contribute in important ways in carrying out modern design techniques which call for smooth contours and surfaces, elimination of clumsy, bulky parts and use of lighter constructions as they apply to flanges, lugs, pockets, and cover plates.

Because Holo-Krome Screws are Thermo-Forged® of alloy steel and scientifically heat treated, they are stronger than conventional screws, size for size. Hence, fewer screws – or smaller screws – are required to fulfill a given holding assignment. As a general rule, a Holo-Krome cap screw is comparable in strength to an ordinary screw of the next larger standard diameter.

    Significant Features:
  • Thermo-Forging®: Preserves the metal fibers – continuous and uncut. The result is a stronger screw with 15-20% increased resistance to fatigue failure.
  • Dimensional Control: Critical areas such as under head bearing surface and radius, run-out thread section and thread profile are designed carefully.
  • Precision Threads: Present methods ensure smooth, burnished threads unsurpassed for uniformity and accuracy.
