Universal screwdriver set Isma IS-5171 — 17-piece bit set for screwdriving tasks

Isma IS-5171 is a 17-piece universal screwdriver bit set designed for general screwdriving tasks. The compact kit groups a variety of interchangeable bits with a compatible screwdriver handle to cover common screw types and sizes found in household repairs, DIY projects and light professional applications. The set emphasizes practicality and space-saving storage while enabling quick bit changes for routine fastening and assembly work.

Advantages

The 17-piece configuration provides a balanced selection of bit types and sizes to address most everyday fastening needs without excess bulk. Interchangeable bits and a single ergonomic handle reduce the number of separate tools required, simplifying transport and storage. Durable bit construction ensures stable fit in screw heads and reliable torque transfer for small to moderate fastening tasks. The compact case keeps all components organized and accessible.

Suitable for

• Household repairs and maintenance
• DIY furniture assembly and home improvement tasks
• Electronics and appliance access where small bit sizes are needed
• Light professional work such as installation and on-site adjustments

Key specifications

• Number of pieces: 17 (bits plus handle)
• Bit types: common slotted, Phillips, Pozidriv, Torx and other standard profiles
• Bit material: hardened steel for wear resistance and strength
• Handle type: compatible quick-change screwdriver handle with magnetic or friction bit retention
• Storage: compact plastic case for organized transport and storage

How to use

Select the bit matching the screw head profile and insert it into the screwdriver handle until it locks in place. Position the bit into the screw head, apply steady axial pressure and turn the handle clockwise to tighten or counterclockwise to loosen. For cross-head or recessed fasteners, ensure the bit fully engages the screw to avoid cam-out. Store bits back in the case after use to preserve bit life and maintain organization.

Usage recommendations

Use the appropriate bit size and profile for each screw to minimize damage to fasteners and bits. Avoid applying excessive torque beyond the bit or screw rating; for heavy-duty or high-torque applications use a dedicated power tool or higher-grade screwdriver set.
