Socket Set Asta long hand sockets 12-point 1/4" on rail, sizes 4–13 mm

Asta long hand sockets 12-point 1/4" on rail, sizes 4–13 mm is a compact set of metric long sockets designed for manual tightening and loosening of hexagonal fasteners in confined, recessed or hard-to-reach areas. The set includes long 12-point sockets compatible with a 1/4" drive and is supplied mounted on a compact rail for neat storage and rapid selection. The tools are intended for general workshop tasks, automotive maintenance and repair operations where access depth or reach is required.

Advantages

The 12-point design permits engagement with fasteners at smaller indexing angles, improving access in tight positions and allowing use on fasteners with minor rounding. Long socket length provides additional reach for recessed bolts and studs while preserving user control with a 1/4" drive interface. The rail mounting keeps sockets organized, prevents loss and speeds up workflow during repeated tasks. The metric range from 4 mm to 13 mm covers common small-to-medium fastener sizes used in electronics, automotive trim, and household repairs.

Suitable for

• Automotive interior and engine bay access where fasteners are recessed
• General workshop maintenance and repair tasks
• Assembly and disassembly of appliances, electronics, and machinery with metric fasteners
• Tight-space fastening where a longer socket reach is required

Key specifications

• Drive size: 1/4" (female square drive for manual tools)
• Socket type: long hand sockets, 12-point (12KT)
• Sizes included: 4 mm, 5 mm, 5.5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm (mounted on rail)

• Storage: compact socket rail for organized storage and transport

How to use

Select the correct socket size from the rail and attach it to a compatible 1/4" ratchet, spinner or extension. Place the long 12-point socket squarely onto the fastener head and apply steady, controlled torque to tighten or loosen. For access in deep recesses, use a 1/4" extension bar together with the socket on the same drive. After use, slide sockets back onto the rail in size order to maintain organization and prevent loss.

Usage recommendations

Use with hand-operated 1/4" drive tools only; avoid applying impact tools or excessive torque beyond the socket and fastener specifications. Inspect sockets regularly for wear or rounding. Store the set on the rail in a dry place to protect the finish and ensure long service life.
