Apex EX-376-4 Socket Extension 1/4 in Drive 4 in Steel

Product Description

The APEX EX-376-4 is a 4-inch socket extension designed for use with 1/4-inch drive ratchets and impact tools. Constructed from steel, it provides a rigid, reliable connection between the drive tool and socket in confined or hard-to-reach fastener locations. The 4-inch overall length adds working clearance without the bulk of a longer extension. This type of extension is a standard accessory in HVAC, plumbing, and electrical service kits where access to fasteners in tight equipment enclosures is routine. It meets ANSI and DIN standards for dimensional accuracy and fit.

The EX-376-4 is suited for light-duty to medium-duty trade applications where a 1/4-inch drive is appropriate — typically panel screws, equipment access covers, junction box hardware, and similar small-fastener work. The 4-inch length is a practical choice for reaching recessed fasteners without requiring an extension set. Trade professionals in HVAC service, electrical, and plumbing commonly carry this size alongside their standard socket sets.

Installation Notes
