Main Applications:

The high-strength bolt test fixture is carefully designed and manufactured by our company according to the relevant national standards GB/T3098.1-2000, using special materials. Through different combinations, it can be used for bolt wedge load test, ordinary tensile test, bolt minimum tensile load test, and nut guaranteed load test. This fixture is clamped into the jaws of the universal testing machine by connecting rods, allowing for various tensile tests. Ordinary hydraulic universal testing machines do not require the addition or modification of other devices.

Main technical indicators:

1. Maximum tensile force of wedge load test: 696kN (M30-10.9s)

2. Minimum tensile load test for bolts: 583kN (M30-10.9s)

3. Nut guarantee load test: 583kN (M30-10.9)

4. Bolt guarantee load test: 466kN (M30-10.9s)

Note: High strength bolt test fixtures above M30 require special ordering
