Key Features and Benefits

• Precision‑Machined Tip: The tip is CNC precision‑machined to deliver a secure fit with slotted screws, reducing cam‑out and increasing accuracy during use.
• Durable Construction: Made from heavy‑duty carbon silicon steel, the shaft is built for strength and long life, with resistance against wear and surface corrosion.
• Ergonomic Handle Design: The tri‑material handle with a large diameter and contoured shape offers firm grip, reduced hand fatigue in repetitive use, and better torque transfer.
• Comfort and Control: A narrow waist and smooth, domed end ensure controlled, comfortable turning movements ideal for both fastening and loosening tasks.
• Clear Size Marking: The handle is often colour‑coded and clearly labelled for quick identification in a tool kit.
• VDE Insulated Options: Some FatMax 4×100 mm screwdrivers in the range are VDE‑approved up to 1000 V for electrical work, with full‑length insulation to protect against live circuits (if the insulated variant).

What This Product Is For

The Stanley FatMax Screwdriver 4 x 100 mm is suitable for tradespeople, machinists, carpenters, and DIY enthusiasts who need a reliable precision slotted screwdriver. Its size makes it useful for general assembly, maintenance tasks, fitting hardware, and work in confined spaces. When selecting a VDE‑rated model, it also serves professional electricians handling live or potentially live electrical installations where safety and compliance with standards are important.

Usage Tips

• Match the screwdriver tip size to the screw head before use to minimise wear and prevent stripping.
• Apply pressure in line with the screw to keep the tip engaged, especially in slotted heads.
• If using the VDE variant for electrical work, always verify insulation integrity before contact with live components.
• Keep the tool clean and free from debris; wiping the shaft and handle after use helps maintain grip and tool condition.

Buying Advice

When buying the Stanley FatMax Screwdriver 4 x 100 mm, consider whether you need the standard parallel (slotted) version or a VDE‑insulated variant. The insulated type, tested up to 1000 V and compliant with EN IEC 60900:2018, is appropriate for electrical applications, whereas the standard model is apt for general mechanical tasks. Compare prices and warranty terms, as some sellers offer extended support or delivery options depending on region. Check that the handle design and grip feel comfortable for prolonged use, especially if you will use the tool frequently.

Common Questions About the Stanley FatMax Screwdriver 4 x 100 mm

Is this screwdriver suitable for electrical work?

Some versions of the Stanley FatMax Screwdriver 4 x 100 mm, particularly VDE‑rated models, are designed with insulated handles tested for use up to 1000 V, making them suitable for electrical tasks. Ensure you select the insulated variant if working near live circuits.

What does the 4 mm x 100 mm measurement mean?

The measurement refers to the blade width (4 mm) and shaft length (100 mm). This size is common for slotted screws and allows access into moderate‑depth fastenings in a range of applications.

How does the handle design affect usability?

The FatMax range features an ergonomic, tri‑material handle with a larger diameter and contoured shape to improve comfort, reduce hand fatigue, and enhance torque control during repetitive use.

Can this tool replace a screwdriver set?

While the Stanley FatMax Screwdriver 4 x 100 mm is effective for specific slotted screws, a full screwdriver set may be more practical for work involving various screw types and sizes. However, for routine flat head tasks, this standalone screwdriver often suffices.
