13Pcs Medium Imperial Ball End Hex Key Set

Product Overview

The 13Pcs Medium Imperial Ball End Hex Key Set is a practical hand tool set designed for working with imperial hex socket screws, bolts, and compatible fasteners. The set includes 13 imperial ball-end hex keys in different sizes for machinery assembly, equipment maintenance, furniture installation, bicycle service, automotive repair, industrial maintenance, and home DIY applications.

The keys are fully induction hardened to support hardness, wear resistance, and resistance to twisting during routine fastening work. The mirror-polished finish gives the set a clean and professional appearance while making it easier to remove oil, dust, and other common residues.

The ball-end tip can engage compatible hex fasteners at an angle, making it useful where straight access is limited or where fasteners are located in restricted spaces. For better torque transfer and fastening control, the straight end is recommended for initial loosening or final tightening of high-torque fasteners, while the ball end is better suited for adjustment, quick turning, and angled-access work.

The exact imperial size range, individual key length, ball-end angle, packaging format, and other specifications should be confirmed according to the specific model and approved sample.

Specifications

Product Features

1. 13-Piece Imperial Size Set

The set includes 13 different imperial hex key sizes to support installation, maintenance, and adjustment of various compatible SAE hex fasteners.

2. Ball End for Angled Access

The ball-end tip can engage compatible hex fasteners at an angle, making it useful in restricted spaces, recessed positions, or areas where straight access is difficult.

3. Straight End for Stable Tightening

The straight end provides more direct contact with the fastener and is suitable for regular tightening, initial loosening, and higher-torque applications.

4. Fully Induction Hardened

The keys are fully induction hardened to help improve hardness, wear resistance, and twisting resistance for repeated daily use.

5. Mirror-Polished Surface

The mirror-polished finish provides a clean metallic appearance and helps make daily cleaning and maintenance easier.

6. Suitable for Multiple Assembly and Repair Tasks

Suitable for compatible applications in machinery, furniture, bicycles, automotive maintenance, industrial assembly, hardware repair, and home DIY work.

7. OEM/ODM Customization Available

Custom laser logos, size markings, packaging, labels, holders, storage cases, set configurations, and private-label options are available.

Applications

The 13Pcs Medium Imperial Ball End Hex Key Set is suitable for compatible imperial hex fastener operations, including:

Machinery installation and maintenance

Industrial equipment repair and production line assembly

Furniture, shelving, and office equipment installation

Bicycle, motorcycle, and sporting equipment maintenance

Automotive repair, engine compartment, and chassis component adjustment

Construction machinery and agricultural equipment maintenance

Electronic housings, instruments, and tool assembly

Hardware repair, workshop tasks, and field installation

Home repair, DIY projects, and toolbox backup

Maintenance of SAE-standard or imported equipment

Usage Tips:

Confirm that the hex key size matches the fastener socket size before use.

The ball end is better suited for angled access and quick adjustment; it is not recommended for final tightening under very high torque.

For tight, rusted, or high-torque fasteners, use the straight end whenever possible.

Do not use the hex keys as pry bars, chisels, hammers, or for other unintended purposes.

Use and Maintenance Tips

Confirm that the hex key size matches the fastener socket size before use.

Fully insert the key into the hex socket before applying force to avoid partial engagement.

Use the straight end whenever possible for initial loosening, final tightening, or higher-torque work.

Use the ball end for angled access, quick turning, and restricted-space adjustment; do not apply excessive torque to the ball end.

Do not use extension pipes, hammering, or other methods to force additional torque.

Do not use on severely damaged, deformed, or incorrectly sized hex fasteners.

Clean oil, dust, moisture, and metal residue from the tools after use.

Store the set in a dry and clean holder, storage case, or toolbox.

Stop using the tool if it becomes bent, cracked, excessively worn at the ball end, or dimensionally damaged.

Safety glasses, gloves, and other suitable personal protective equipment are recommended when working with machinery or high-torque applications.

FAQ

1. Is this hex key set imperial or metric?

This is an imperial hex key set designed for compatible SAE or imperial hex fasteners. The exact size list should be confirmed according to the specific model.

2. What is the purpose of the ball end?

The ball end allows angled engagement with compatible hex fasteners, making it suitable for restricted spaces, areas where straight access is difficult, or quick adjustment tasks. The ball end is not recommended for final tightening under high torque.

3. What are the benefits of full induction hardening?

Full induction hardening helps improve the key’s hardness, wear resistance, and twisting resistance, making it suitable for routine and repeated fastener work. Actual service life still depends on applied torque, frequency of use, and maintenance.

4. What are the features of the mirror-polished finish?

The mirror-polished surface provides a clean metallic appearance and makes it easier to remove common oil, dust, and fingerprints. Actual corrosion resistance also depends on storage conditions and regular maintenance.

5. Do you offer OEM/ODM customization?

Yes. OEM/ODM services are available for logos, size markings, imperial or metric specifications, quantity configuration, holders, storage cases, packaging, labels, barcodes, and tool set customization. Please provide your estimated order quantity, size list, target market, and packaging requirements for evaluation.
