A torque wrench end fitting or insert is placed on the end of a suitable torque wrench, enabling the torque wrench to apply torque to a specific fastener type.
Frequently Asked Questions about Torque Wrench End Fittings
What are torque wrench end fittings and why would I need them?
Torque wrench end fittings allow you to adapt your torque wrench to different types of fasteners. They’re essential for jobs that require specific fastener engagement, like working with hex bolts, Torx screws or specialised fasteners.
Are all torque wrench end fittings compatible with every torque wrench?
No, not all end fittings are universally compatible. Always check your torque wrench’s specifications and ensure the fitting’s size and attachment method match your tool.
How do I install an end fitting on my torque wrench?
End fittings are typically attached by sliding them onto the wrench’s square drive or another connector. Ensure the fitting is securely fastened to avoid slippage during use.
What is the benefit of using interchangeable end fittings?
Interchangeable end fittings make a torque wrench more versatile by allowing it to work with a range of fasteners. This eliminates the need for multiple tools and ensures precision across various tasks.
What industries require specific torque wrench end fittings?
Machine assembly, automotive repairs, the renewable energy sector and the aerospace industry often need specific fittings, such as open-end or flare-nut fittings, to apply precise torque to specialised fasteners.
Can I use a torque wrench end fitting for tight spaces?
Yes, there are end fittings designed specifically for tight or awkward spaces. Look for slim-profile or angled fittings that provide better access to hard-to-reach fasteners.
How do I store torque wrench end fittings?
Keep end fittings clean and organised in a protective case. This prevents contamination, rust and damage, ensuring they’re ready for accurate use when needed.
The ratchet on my torque wrench end is jammed, is there anything I can do?
In some cases a jammed ratchet can be fixed by opening it up, cleaning it and then reassembling the parts.
Should I lubricate my ratchet?
Yes, you should lubricate the ratchet on your torque wrench end with a low friction oil. Lubricant will help increase the life and smooth running of the ratchet mechanism.
Are there calibration considerations when changing torque wrench end fittings?
Yes, changing the length or type of end fitting can affect torque output. Some torque wrenches may need recalibration or adjustment when using offset or extended fittings to maintain accuracy.
What materials are torque wrench end fittings made from?
Torque wrench end fittings are typically made from hardened steel or chrome vanadium for strength and durability. These materials resist wear and deformation, ensuring reliable performance under repeated use.
