Socket bit Torx with hole 1/4" Jonnesway T20 x 37 mm (S08H220)

Jonnesway 1/4" Torx socket bit T20 x 37 mm (S08H220) is a force-transmitting interchangeable bit designed for use with 1/4" drive ratchets, screwdrivers and bit holders. The bit features a Torx T20 profile with a central through-hole, allowing engagement with tamper-resistant (security) Torx fasteners. With a 37 mm overall length it provides extra reach for recessed or hard-to-access fasteners commonly encountered in mechanical and automotive repair.

Advantages

The Torx tip with central through-hole enables reliable engagement with security fasteners while maintaining torque transmission efficiency. Constructed for compatibility with standard 1/4" drive tools, the bit offers consistent fit to T20 fasteners and precise seating to reduce cam-out. Its 37 mm length balances reach and control for tasks in confined spaces. The hardened working profile and machined geometry ensure durability and repeatable performance under regular workshop use.

Suitable for

• Removal and installation of Torx T20 security fasteners in electronics, appliances and automotive components
• Use with 1/4" drive ratchets, drivers and bit holders for general maintenance and repair
• Accessing recessed or tight fasteners where additional bit length is required

Key specifications

• Drive size: 1/4" (6.35 mm) compatible
• Torx profile: T20 with central through-hole (tamper-resistant)
• Overall length: 37 mm
• Material and heat treatment: hardened working tip for wear resistance
• Fitment: designed to match standard Torx dimensions for secure engagement

How to use

Select a compatible 1/4" drive ratchet, screwdriver or bit holder and insert the socket bit until it seats securely. For security Torx fasteners, align the bit so the central hole accommodates the fastener’s pin, then apply steady axial pressure while turning to engage the head. Use controlled torque appropriate to the fastener and application to avoid stripping; if using a torque wrench, observe the required torque settings for the assembly. After use, inspect the tip for wear and store in a bit holder to maintain geometry.

Usage recommendations

For reliable results, use the bit with properly sized 1/4" drive tools and avoid excessive side loading. Replace the bit when rounded edges or visible wear occur to prevent damage to security Torx fasteners. Keep the bit clean and free of debris to ensure accurate fit and torque transfer.
