Product Information
Full details
The S&R 13-piece Allen key set is an essential tool collection designed for mechanics, technicians, and DIY enthusiasts who require precision in tight spaces. Its primary benefit is the ball-end design, which allows for effective fastening at inclined angles up to 25 degrees, though users should be mindful that high-torque applications at extreme angles can increase the risk of rounding out fasteners.

FAQs
Are these keys suitable for use with power tools?
No, these are strictly hand tools. Using them with power drills or impact drivers can snap the keys or strip the fasteners.
Can I use the ball-end to fully tighten a bolt?
The ball-end is designed for quick spinning and reaching awkward angles. It is best to use the straight end for the final tightening or breaking loose a stuck bolt.
What is the smallest and largest size in this set?
The set ranges from 1.27 mm at the smallest to 10 mm at the largest.
Is the steel magnetic?
While the tools are made of chrome vanadium steel, they are not permanently magnetized. You may need a magnetic pickup tool for dropped screws.
How do I maintain the finish?
Keep them dry and store them in the provided holder. A quick wipe with a light machine oil helps prevent oxidation.
Troubleshooting
Key slips out of the bolt head
Ensure you are using the correct size and that the hex socket is free of debris. Use the straight end for better grip if the bolt is tight.
Key feels loose in the fastener
Verify that you have not mistaken a standard SAE bolt for a metric one. Check for stripped edges on the fastener socket.
Difficulty reaching the fastener
Utilize the ball-end to approach at an angle, or remove the obstructing part to allow for a direct straight-on approach.
Pros and Cons
Pros
- High-quality chrome vanadium steel construction
- Ball-end design allows for off-axis turning
- Extensive size range covers almost all common metric applications
- Compact folding holder keeps tools organized
Cons
- Ball-end is not suitable for high-torque final tightening
- Not intended for use with power tools or impact drivers
- Requires manual cleanup to prevent surface corrosion in humid workshops
Setup, Compatibility & Care
This set is designed for standard metric hex head fasteners. To ensure longevity, keep the keys clean and dry, especially after use in moist environments. While the chrome vanadium steel is rust-resistant, a light wipe with an oily rag before storage in the holder will help maintain the finish. Avoid using these keys as levers or prying tools, as this can bend the hardened steel. The included folding holder is marked with size indicators, allowing you to quickly return each key to its correct slot after use.
