Proline Torx Bit Socket 1/4" T9 x 37mm (Proline 58127)

Proline Torx Bit Socket 1/4" T9 x 37mm is a single replaceable bit socket made for 1/4" drive ratchets, bit drivers and adapter sets. The T9 Torx profile delivers positive engagement with matching Torx fasteners, while the 37 mm overall length enables access to recessed or slightly deep screws commonly found in electronics, household appliances and compact mechanical assemblies.

Advantages

This Torx bit socket combines a standardized 1/4" square drive interface with a precision-formed T9 tip to minimise cam-out and wear during repeated use. Its single-piece construction provides consistent alignment in ratchet or driver tools and the 37 mm length balances reach and control for working in confined spaces. The socket is compatible with common adapters and extension bars for flexible use in professional or DIY tool sets.

Suitable for

• Repair and assembly of consumer electronics (small devices, circuit boards)
• Maintenance of household appliances and fixtures
• Work on small mechanical components and hobby projects
• Use with 1/4" ratchets, bit drivers, and adapter sets

Key specifications

• Drive size: 1/4" square drive
• Tip profile: Torx T9
• Overall length: 37 mm
• Material: heat-treated tool steel (typical for this class of bit sockets)
• Compatibility: designed for use with 1/4" ratchets, bit holders and adapters

How to use

Insert the 1/4" square drive into a compatible ratchet, bit holder or driver. Engage the T9 Torx tip with the matching fastener head, ensuring the tip sits fully in the recess before applying torque. Turn the ratchet or driver steadily to tighten or loosen the fastener; avoid excessive side load to reduce tip wear and risk of rounding the fastener. When working in tight or recessed areas, use appropriate extensions or universal joints to achieve the required access while keeping the bit aligned with the fastener.

Usage recommendations

Use the Proline T9 37 mm Torx bit socket with properly sized 1/4" drive tools and avoid applying impact-style torque unless the bit is explicitly rated for impact use. Store the socket in a bit holder or tool organiser to protect the tip from damage and inspect the tip before use to ensure secure, reliable engagement with Torx fasteners.
