Bulk Direct Tension Indicator Washers – Plain or Galvanized Finish for A325 Bolts (Made in USA)

Bulk Direct Tension Indicator Washers – Plain & Hot Dipped Galvanized (HDG) for A325 Bolts (Made in USA)

Enhance the safety and reliability of your structural assemblies with our premium Direct Tension Indicator (DTI) Washers, now available in both Plain Finish and Hot Dipped Galvanized (HDG) versions. Manufactured in the USA, these washers are designed specifically for use with A325 structural bolts, providing a direct method of tension verification during installation.

Why Choose Our Direct Tension Indicator Washers?

Direct Tension Indicator Washers are engineered with protrusions on the bearing surface that deform under load, allowing installers to verify proper tension has been achieved without the need for specialized equipment. This ensures that bolted connections meet the required specifications for structural integrity, which is critical in construction and infrastructure projects.

Available Finishes:

• Plain Finish: Suitable for indoor applications or environments where corrosion is not a significant concern.
• Hot Dipped Galvanized (HDG): Provides superior corrosion resistance, ideal for outdoor or harsh environments.

Key Benefits:

• Accurate Tension Verification: Protrusions compress at a predetermined load, indicating proper bolt tension.
• Enhanced Safety: Ensures structural connections meet specified tension requirements, reducing the risk of joint failure.
• Easy Installation: Visual inspection of protrusion compression simplifies the tensioning process.
• Made in the USA: Manufactured with strict quality control standards for dependable performance.
• Choice of Finishes: Select between Plain and HDG finishes to suit your project requirements.
• Bulk Availability: Ideal for large construction projects requiring significant quantities.

Available Sizes:

Our bulk Direct Tension Indicator Washers are available in the following US / Inch sizes to meet your project requirements:

• 3/4", 7/8" and 1"

Ideal Applications:

These DTI washers are essential for structural steel connections in construction projects such as bridges, buildings, towers, and other infrastructure requiring high-strength bolted connections. They provide a reliable method for verifying bolt tension, crucial for the integrity and safety of the structure.

Technical Specifications:

• Material: Medium Carbon Steel
• Finishes Available:
  • Plain Finish: Uncoated steel suitable for non-corrosive environments.
  • Hot Dipped Galvanized (HDG): Thick zinc coating for superior corrosion resistance.
• Compatible Bolts: Designed for use with A325 structural bolts
• Standards: Manufactured to meet ASTM F959 specifications
• Origin: Made in the USA
• Operation: Protrusions compress under specified tension to indicate proper bolt preload

Installation Guidelines:

To ensure accurate tensioning:

• Place the DTI washer under the bolt head or nut with protrusions facing the bearing surface.
• Tighten the bolt until the specified gap between the washer and bearing surface is achieved, indicating proper tension.
• Refer to ASTM F959 and project specifications for detailed installation procedures.
