In the demanding world of industrial maintenance, construction, power generation, refining, and heavy manufacturing, proper bolt tensioning is critical. A single mis-tensioned bolt can cause leaks, equipment failure, downtime, or safety incidents. At American Bolting, we specialize in advanced bolting solutions that prioritize safety, accuracy, and efficiency. That’s why we proudly offer, rent, service, and calibrate Skidmore-Wilhelm bolt testing equipment, the trusted gold standard for verifying true bolt preload.
What Is Skidmore-Wilhelm Bolt Testing Equipment?
Since the 1950s, Skidmore-Wilhelm has set the benchmark for bolt tension measurement. Their hydraulic bolt tension calibrators (commonly called Skidmore testers) directly measure the actual clamping force (tension) applied to a bolt assembly, far more reliable than torque values alone, which can vary due to friction, lubrication, and other variables.
Popular models like the Skidmore Model MZ and others support a wide range of bolt sizes and are compatible with manual, electric, pneumatic, and hydraulic tools. These testers are indispensable for:
- Pre-Installation Verification (PIV) testing
- Rotational Capacity (RoCap) testing
- Calibrating torque wrenches and tensioning systems
- Meeting ASTM F3125, AISC, RCSC, and other strict specifications
From structural steel projects to pressure vessels, turbines, and heavy flanges, Skidmore equipment delivers the precise, repeatable tension data you need for confidence and compliance.
Why Accurate Bolt Tension Testing Matters
Torque is simple to measure, but tension is what truly secures the joint. Without proper verification, variations in friction and tool performance can lead to:
- Loose connections causing vibration, leaks, or loosening over time
- Over-tensioned bolts that stretch, crack, or damage components
- Failed inspections, costly rework, project delays, or liability issues
Skidmore-Wilhelm testers remove the guesswork. They provide documented proof of correct preload, helping you maintain safety, pass inspections, and minimize downtime.
