Grade 8.8 High Tensile Hex Head Set Screws | DIN 933, BZP Finish

The Professional's Choice for High-Strength, Reliable Fastening

Secure your projects with confidence using our comprehensive range of Grade 8.8 High Tensile Hex Head Set Screws. Manufactured to the DIN 933 standard, these fully threaded bolts provide maximum clamping force and are the go-to fastener for demanding applications in construction, automotive, and machinery assembly. Their high-strength construction and corrosion-resistant finish make them an essential component for any professional or serious DIY enthusiast.

Our hex set screws are forged from Grade 8.8 high tensile steel, a medium carbon steel that has been quenched and tempered to provide superior strength and durability compared to standard mild steel bolts. his makes them perfectly suited for high-stress applications where reliability and resistance to wear and tear are critical. Whether you are assembling steel frameworks, repairing engine components, or building heavy-duty machinery, these bolts provide the secure hold you need.

Conforming to the DIN 933 standard, each set screw is fully threaded from just below the head to the tip. This design ensures maximum thread engagement in tapped holes or when used with a nut, providing excellent grip and distributing clamping pressure evenly along the entire length of the fastener. This makes them ideal for applications where a strong, vibration-resistant connection is paramount.

To protect against corrosion in indoor or dry environments, each bolt is finished with a Bright Zinc Plating (BZP). This sacrificial zinc layer not only offers moderate rust protection but also provides a clean, professional finish to your work.
