Sk 19751 Ball Hex Bit Socket Set 3/8 in Drive 7 Pc

Product Description

The SK 19751 is a 7-piece ball hex bit socket set designed for 3/8 inch drive ratchets and extensions. It covers hex sizes from 1/8 inch through 3/8 inch, giving technicians a full fractional-inch range in a single set. The ball-end design allows engagement at off-axis angles, which is useful when fastener access is restricted. Built from steel, this set is suited for HVAC service, plumbing rough-in, electrical panel work, and general mechanical tasks where hex-head fasteners are common. Licensed tradespeople and experienced service techs are the primary users.

This socket set is appropriate for residential and light commercial service work. It fits standard 3/8 inch drive ratchets, breaker bars, and torque wrenches. The seven included sizes cover the most common fractional-inch hex fasteners encountered in equipment installation and maintenance. The ball-tip geometry is particularly useful in tight equipment bays and junction boxes where a straight approach to the fastener is not possible.

Installation Notes

Always power down or shut off the equipment being serviced before using hex bit sockets on fasteners securing electrical enclosures, access panels, or mechanical components. Ensure the socket is fully seated on the fastener before applying torque to avoid rounding hex recesses. Store the set in its tray or case to prevent loss of individual pieces on the job site.
