Extension bar YATO YT-1248, chrome-molybdenum steel, length 254 mm, 1 pc

YATO YT-1248 is a single-piece extension bar made from chrome-molybdenum steel with a length of 254 mm. It is designed to extend the reach of sockets and ratchets, enabling access to recessed or hard-to-reach fasteners. The solid construction improves torsional strength and resists wear under repeated use in automotive, maintenance and assembly environments.

Advantages

The chrome-molybdenum steel construction provides high tensile strength and improved resistance to twisting compared with standard tool steels. A single-piece design minimizes weak points and delivers consistent torque transfer from ratchet to socket. The 254 mm length offers extended reach for work in engine bays, behind panels or inside machinery while remaining compact enough for toolboxes. The product surface finish reduces corrosion and facilitates cleaning after use.

Suitable for

• Automotive repair and servicing where fasteners are recessed or hard to reach
• Industrial maintenance and assembly operations requiring extended reach
• Home workshop tasks involving machinery, appliances, or structural components
• Use with compatible sockets and ratchets for fastening and loosening bolts

Key specifications

• Material: chrome-molybdenum (Cr-Mo) steel
• Length: 254 mm
• Construction: single-piece bar for improved torsional strength
• Compatibility: designed for use with standard sockets and ratchets of matching drive size
• Finish: corrosion-resistant surface treatment

How to use

Select a socket that matches the fastener size and attach it securely to the extension bar. Connect the opposite end of the extension bar to a compatible ratchet or drive tool. Position the socket over the fastener and apply steady torque using the ratchet, taking care to align the tool to avoid side loads. After use, wipe the extension bar clean of grease and debris and store it with other drive tools to prevent damage.

Usage recommendations

Use the extension bar only with sockets and drive tools that match the bar's drive size. Avoid using cheater bars or excessive impact forces that exceed the design limits of chrome-molybdenum hand tools. Inspect the extension bar for wear or damage before use and replace it if deformation or cracking is observed.
