Tekton SHB91315 Long Hex Bit Socket Set 3/8 Drive 19 Pc

Product Description

The TEKTON SHB91315 is a 19-piece long hex bit socket set built for 3/8 inch drive ratchets and extensions. It covers both standard and metric hex sizes, ranging from 1/8 inch through 3/8 inch and 3 mm through 10 mm, making it a versatile set for fastener work across a wide variety of applications. Each bit socket features an extended length of 6 inches for reaching fasteners in recessed or tight spaces. The set is constructed from steel and ships in a plastic case that keeps every piece organized and indexed. Licensed trades and experienced DIYers alike reach for this type of set when standard-depth sockets cannot access the fastener head.

This set is suited for residential and commercial service work involving hex-head fasteners on HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies. The combination of standard inch and metric sizes in a single case reduces the need to carry two separate sets on a job. The long bit socket format is particularly useful when fasteners are seated deep inside equipment panels, valve bodies, or motor housings where a short bit socket or L-key will not fit cleanly.

Key Features

• 19-piece set covers 1/8 inch through 3/8 inch standard and 3 mm through 10 mm metric hex sizes
• Extended overall length of 6 inches for deep-reach fastener access
• 3/8 inch drive compatible with standard ratchets, extensions, and flex handles
• Steel construction for durability under torque
• Organized plastic case included for storage and transport
• Lifetime warranty from the manufacturer

Compatibility

Designed for use with any 3/8 inch drive ratchet, breaker bar, torque wrench, or extension. Fits standard 3/8 inch drive tool systems used across HVAC, plumbing, electrical, and general mechanical service trades.

Installation Notes

Seat each bit socket fully onto the drive before applying torque to prevent slipping and rounding of the fastener head. Inspect bit tips for wear before use, as a worn hex tip can damage fastener sockets. Always de-energize equipment and relieve system pressure before removing hex fasteners on mechanical or fluid-carrying assemblies. This set is intended for hand-tool use with a 3/8 inch drive ratchet or wrench, not for impact driver use unless the sockets are specifically rated for impact.
