Interlocking ID Tube Clamp Frequently Asked Questions
What is an interlocking ID tube clamp used for?
It is used to connect or locate tube sections from the inside diameter side, especially in removable fabricated tube assemblies.
Which dimensions matter most for fitment?
Start with tube size / ØA, ØB, wall thickness, C dimension, and screw size.
Where are ID tube clamps commonly used?
They are commonly used in roll cages, chassis fabrication, removable tube sections, light bar mounts, bumpers, and custom tube connector systems.
How is this different from an OD tube clamp?
An ID tube clamp is designed around internal/interlocking tube engagement, while an OD tube clamp is selected around outside-diameter tube mounting.
What material and bolt information is listed?
The catalog lists 4130 chromoly steel or carbon steel material, plus two Grade 10.9 bolts with black powder coated or silver zinc plated finish options.
Can SYZ support custom tube clamp dimensions?
Yes. Send tube OD, wall thickness, screw size, drawing, material request, and volume for review.
