Question 1

What is the SATA GL80108A Extra Long Ball Point Hex Key 4mm and what is it used for?

Accepted Answer

The SATA GL80108A is an extra-long 4 mm ball-point hex key designed to reach deep or hard-to-reach fasteners. Its ball-point tip allows angled entry (up to about 25 degrees) for easier engagement in awkward positions, while the extended length provides improved leverage. It’s ideal for automotive repairs, general maintenance, and assembly tasks where standard-length keys can’t reach fasteners.

Question 2

What are the main specifications of this hex key?

Accepted Answer

Key specs include a 4 mm hex size, an extra-long length (up to 30% longer than standard), a ball-point tip for angled entry, chrome vanadium steel (Cr-V) construction, a rust-resistant coating, chamfered tips for fast insertion, easy-to-read size markings, and an ergonomic handle design for comfortable, controlled use.

Question 3

How does the ball point tip benefit use?

Accepted Answer

The ball-point tip allows entry into fasteners at small angles (up to approximately 25 degrees), making it easier to engage fasteners when straight alignment isn’t possible. This reduces the risk of cam-out and enables access in tight or awkward spaces.

Question 4

How does the extra-long design improve access and leverage?

Accepted Answer

The extended reach lets you access fasteners that sit deep within assemblies or in cramped areas. The longer handle also increases torque and leverage, meaning you can tighten or loosen fasteners with less effort compared with standard-length keys.

Question 5

What materials and finish are used for durability?

Accepted Answer

The tool is made from chrome vanadium (Cr-V) steel for strength and durability, with a rust-resistant coating to resist corrosion. Chamfered tips aid quick insertion and a secure fit into fasteners, while easy-to-read size markings help with quick identification.

Question 6

What applications is this tool ideal for?

Accepted Answer

It’s well-suited for automotive work, appliance repair, general mechanical maintenance, and any task requiring access to recessed or tightly spaced fasteners where a regular-length hex key won’t reach.

Question 7

How should I use and maintain this hex key to extend its life?

Accepted Answer

Keep it dry and clean after use, wipe away oil or debris, and store it in a dry tool chest or tray to prevent rust. Use the tool for its intended purpose, avoid over-torquing, and periodically check for any signs of wear or burrs on the tip.

Question 8

How is this 4mm extra-long ball-point hex key different from standard-length hex keys?

Accepted Answer

Compared to standard-length keys, the GL80108A offers up to 30% more length for deeper access and greater leverage, plus a ball-point tip for angled entry. This combination reduces effort and improves accessibility in confined spaces.

Question 9

How does it compare to other 4mm ball-point hex keys available on Fepy?

Accepted Answer

On Fepy, you can consider alternatives like SATA GL80108B (4mm, extra-long ball-point hex key) for a similar 4mm option with potential minor build differences, available at https://fepy.com/product/sata-gl80108b-extra-long-ball-point-hex-key-4mm. Another option is SATA GL80110A (5mm) for a different size choice if your fasteners require a 5 mm size; available at https://fepy.com/product/sata-gl80110a-extra-long-ball-point-hex-key-5mm. These provide size/length variations to fit different applications while maintaining the ball-point feature and extended reach.

Question 10

Are there safety considerations I should keep in mind when using an extended-reach ball-point hex key?

Accepted Answer

Yes. Use the correct 4 mm size for the fastener to avoid rounding corners. Apply steady, controlled force rather than sudden jerks, keep the tool perpendicular to the fastener when possible, and wear eye protection if working in dirty or loose-part environments. Avoid using damaged or bent keys, and store tools properly to prevent rust or corrosion.

Question 11

What value does the extended reach provide in terms of leverage and torque?

Accepted Answer

The extended reach increases leverage by giving you more surface area to apply torque, enabling smoother turning with less muscular effort. This is especially helpful when fasteners are recessed, located in tight spaces, or require higher torque to function correctly without slipping.

Question 12

Is this hex key compatible with metric fasteners, and will it fit securely into fasteners?

Accepted Answer

Yes. The 4 mm hex size is designed for metric fasteners. The precise fit minimizes slippage and reduces the risk of rounding the fastener corners. Chamfered tips and a snug fit enhance insertion reliability and control during use.
