Sk 19734 Hex Bit Socket Set 9 Pc 3/8 1/2 Drive Metric

Product Description

The SK 19734 is a 9-piece metric hex bit socket set covering both 3/8 inch and 1/2 inch drive sizes. The set spans a hex size range of 4 mm through 17 mm, giving technicians and trade professionals a compact but versatile selection for fastener-heavy service work. All sockets are steel construction. The 3/8 inch drive sockets cover 4, 5, 6, 7, 8, and 10 mm hex sizes, while the 1/2 inch drive sockets cover 12, 14, and 17 mm. This single set eliminates the need to carry two separate sets when switching between drive sizes on the job.

This hex bit socket set is suited for HVAC, plumbing, and electrical service work where metric hex-head fasteners appear on equipment panels, valve assemblies, motor mounts, and enclosures. The dual-drive configuration makes it practical for both tight-clearance tasks on the 3/8 inch side and higher-torque applications on the 1/2 inch side. It is a standard addition to a field technician's socket collection for residential and light commercial service calls.

Installation Notes

Use with a calibrated torque wrench when fastener torque specifications are critical to the application. Ensure the correct drive size is matched to the ratchet or breaker bar before applying force. Inspect sockets for wear or cracking before use, and do not use damaged sockets. Store in a dry location to prevent corrosion on the steel finish.
