Alloy Steel Socket Head Cap Screws - High Tensile Fasteners

When standard fasteners aren't enough, our Alloy Steel Socket Head Cap Screws deliver the ultimate in mechanical strength and precision. With a massive tensile strength of 170,000 psi, these fasteners are significantly stronger than Grade 8 steel screws, making them the industry standard for high-stress applications in machinery, automotive assembly, and heavy industrial equipment.

Engineered for Performance:

  • Maximum Strength: Manufactured from high-grade alloy steel to meet ASTM A574 standards, ensuring reliable performance under extreme loads.
  • Precision Drive: The internal hex (socket) drive allows for higher torque applications and a cleaner, low-profile install compared to standard hex bolts.
  • Versatile Finishes: Available in Black-Oxide for mild corrosion resistance in dry environments or Zinc-Plated for enhanced protection in wet conditions.
  • Standard & Fine Thread: Choose coarse threads for general-purpose use or fine threads for superior vibration resistance and fine adjustments.

Compliance & Quality Standards:

  • Material Quality: Meets ASTM A574, ASTM A574M, and ISO 898-1.
  • Dimensional Standards: Complies with ASME B18.3 and ISO 4762.

The Industrial Standard for High-Torque Fastening. Whether you are performing MRO repairs or engineering a new machine, TACT Industrial provides the high-tensile hardware you can trust.
