Torque Wrenches / Torque & Tension Testing Equipment

Greenslade offers precision torque wrenches and tension testers designed to support a range of fastener testing applications. Whether you’re verifying torsional strength or determining torque-tension relationships, our tools provide the accuracy and repeatability manufacturers need.

Torque Wrenches
Torque wrenches are essential for evaluating a wide range of fastener performance metrics, including:

  • Torsional strength of tapping screws
  • Drive torque for thread rolling screws
  • Hydrogen embrittlement testing for electroplated screws and bolts
  • Prevailing torque and removal torque for locknuts and lock screws
  • Torque-tension testing for screws, structural bolts, and locking fasteners

Each Greenslade torque wrench meets the industry-standard accuracy of ± 1%. For best performance, wrenches should not be used in the lower 20% of their rated capacity.

Choose between dial torque wrenches—featuring a memory needle and easy-to-read face—or digital models compatible with our data collection software for real-time reporting.

Available Dial Torque Wrenches:

  • TWI-030: 6–30 inch-pounds
  • TWI-075: 15–75 inch-pounds
  • TWI-300: 60–300 inch-pounds
  • TWF-025: 5–25 foot-pounds
  • TWF-050: 10–50 foot-pounds
  • TWF-100: 20–100 foot-pounds
  • TWF-150: 30–150 foot-pounds
  • TWF-250: 50–250 foot-pounds
  • TWF-600: 120–600 foot-pounds
  • TWF-1000: 200–1000 foot-pounds

Tension Testers

Tension Testers determine how much tension (stretching force) is created when torque is applied to bolts in real-world applications. Because friction varies across bolt types and finishes, torque values alone can be misleading. Testing ensures fasteners meet performance expectations in assemblies.

Greenslade tension testers use hydraulic load cells to measure tension force as bolts are tightened. Combined with a torque wrench, this system allows manufacturers to accurately determine the torque-to-tension relationship for any fastener system.

Tension Tester Models:

  • Model S: #6, #8, #10, 1/4 tooling; tension capacity 5,000 lbs
  • Model J: #10 through 9/16 tooling; tension capacity 30,000 lbs
  • Model RL: 5/8 through 1-1/4 tooling; tension capacity 110,000 lbs
