Ruuvauskärki KS Tools 911.7560 Hex 3 mm pituus 75 mm

The KS Tools 911.7560 Hex 3 mm, 75 mm screwdriver bit is a precision tool designed for accurate fastening and loosening of hex screws. With a 3 mm hex tip and an extended 75 mm length, this bit provides access to recessed fasteners while maintaining control and torque transfer. The bit's compact mass and precise geometry make it suitable for delicate assembly and maintenance work in electronics, instrumentation, and mechanical applications.

Advantages

The bit is manufactured from durable steel with a hard-wearing finish that resists wear from repeated engagement with hex sockets. Its 75 mm length allows reach into tight or recessed areas without compromising stability, and the 3 mm tip offers precise fit to minimize cam-out and fastener damage. Lightweight construction supports extended manual or powered use with reduced operator fatigue, while consistent tip dimensions ensure repeatable performance across tasks.

Suitable for

• Precision electronics assembly and repair
• Instrument and meter maintenance
• Small machinery and mechanical fastening
• Accessing recessed hex fasteners in housings and panels

Key specifications

• Tip type: Hex (internal hexagon)
• Tip size: 3 mm
• Overall length: 75 mm
• Weight: 20 g
• Material: high-strength tool steel with wear-resistant finish
• Drive interface: standard 1/4" hex shank compatible with most bit holders and drivers

How to use

Insert the 1/4" hex shank into a compatible screwdriver handle, bit holder, or powered driver. Ensure the bit is seated fully to prevent slippage. Align the 3 mm hex tip with the fastener and apply steady axial pressure while turning to engage threads. For powered drivers, use low to moderate speed and controlled torque to avoid over-tightening or damaging small fasteners. After use, inspect the tip for deformation and store in a protective bit holder to preserve geometry.

Recommendations

Use the bit with appropriately sized drivers and torque settings suited to small hex fasteners. Avoid excessive force or using the bit on damaged fasteners. Regularly inspect and replace the bit when wear affects fit or increases the risk of cam-out.
