Hex Precision Keys Set 7 pcs, högert technik HT1W800 — sizes 0.71–3.00 mm

Set of 7 precision hex (Allen) keys from högert technik, model HT1W800. This compact set includes finely ground hex keys in seven small sizes from 0.71 mm up to 3.00 mm, designed for accurate fastening and adjustment of electronics, optical instruments and other assemblies that use miniature hex fasteners. The tools are intended to deliver a close-tolerance fit for precise torque transfer and reduced fastener wear during routine maintenance, repair and assembly tasks.

Advantages

The keys are manufactured to tight dimensional tolerances to ensure reliable engagement with small hex heads, minimising rounding and slippage. Their small sizes cover a broad range of miniature fasteners commonly found in electronics, instruments and optical devices. The compact set format keeps tools organised and portable for bench work or field service. Materials and heat treatment are selected to provide sufficient hardness for durability while preserving a precise tip profile.

Suitable for

• Assembly and adjustment of electronic devices and circuit boards
• Maintenance and repair of optical equipment and instruments
• Fine mechanical assemblies, models and miniature fixtures
• Precision fastening in hobbyist and professional applications

How to use

Select the hex key that matches the fastener size and insert the tip squarely into the hex recess to ensure full contact between tool and fastener. Apply steady, controlled torque and avoid excessive force to prevent tool or fastener damage. For recessed or hard-to-reach screws, use the longer end of the key for additional reach or the shorter end for increased leverage, depending on space and torque requirements. After use, return keys to the holder to maintain organisation and protect tip geometry.

Usage recommendations

Use these precision hex keys for tasks that require accurate torque control and minimal fastener wear. Regularly inspect tips for rounding and clean contacts before use. Store the set in its holder and avoid using the keys as pry bars or chisels to preserve tip shape and ensure consistent performance.
