Screwdriver Bit KS Tools 911.5130 Hex 12mm 30mm

The KS Tools 911.5130 Screwdriver Bit Hex 12mm 30mm is a single replacement bit engineered for tasks requiring a 12mm hex interface and a compact 30mm length. Manufactured by ks tools, this bit is intended for use with compatible bit holders, ratchets and screwdrivers that accept standard hex bits. The design focuses on accurate fit with hex fasteners, consistent torque transfer and a size suitable for confined spaces or assemblies where a shorter bit is advantageous.

Advantages

This 12mm hex bit is made to provide a precise fit in hex recesses and minimize cam-out. Its 30mm overall length balances reach and control, reducing leverage that can cause over-torquing in sensitive joints. The material and heat treatment deliver durability under repeated use and improved resistance to wear compared with untreated bits. The compact form factor aids handling in tight access areas and simplifies bit storage in standard bit sets.

Suitable for (tasks / use cases)

• Fastening or loosening hex bolts and screws with a 12mm hex drive
• Automotive repair where short bit length is needed for limited clearance
• Assembly and maintenance of machinery, equipment and furniture with hex fasteners
• Use with bit holders, quick-release chuck drivers and manual ratchets

Key specifications

• Tip type: Hex
• Hex size: 12 mm
• Overall length: 30 mm
• Compatibility: Standard 1/4" hex bit holder interfaces (where applicable)
• Intended use: Manual and light power-assisted fastening

How to use

Insert the KS Tools 12mm hex bit into a compatible bit holder or chuck until it seats securely. Select the appropriate driver or ratchet and position the bit into the hex fastener, ensuring full engagement before applying torque. For manual use, apply steady, controlled force to avoid slipping; for powered drivers, use low to moderate speed and torque settings to prevent damage to the fastener or workpiece. Inspect the bit for wear or deformation before use and replace if the tip shows rounding or chipping.

Usage recommendations

Use the bit with matched hex fasteners and appropriate torque settings. Store in a dry environment to avoid corrosion and keep a spare bit available when working in critical applications. Do not use a damaged bit; excessive force or impact on the bit beyond its intended use can reduce performance and safety.
