The BSC PREFERRED GS050816 is a 9-in-1 fold-up hex key set designed for tradespeople and technicians who need a compact, multi-size Allen key solution on the job. The set includes nine fractional-inch SAE key sizes housed in a single folding plastic handle with a comfort grip. All keys fold neatly into the handle for safe storage and quick deployment. This tool is suited for equipment service, panel work, and mechanical fastener tasks where multiple hex sizes are commonly encountered in a single job. It is a hand-carry tool appropriate for HVAC techs, plumbers, electricians, and general maintenance professionals.
This fold-up hex key set is intended for light to medium-duty service work in residential and commercial trade applications. It covers nine of the most commonly used fractional-inch hex sizes, making it practical for servicing set screws, access panels, equipment covers, and mechanical assemblies. The compact folding design reduces clutter in a tool bag or service pouch. It is well-suited for field technicians who need a quick-grab multi-size hex solution without carrying a full loose-key ring.
Designed as a general-purpose fractional-inch SAE hex key set compatible with standard hex fasteners across HVAC, plumbing, electrical, and mechanical service applications.
This tool requires no installation. Always select the correct key size before applying torque to avoid rounding hex fastener sockets. Inspect keys for wear or deformation before use on critical fasteners. Store with keys folded closed to protect both the tool and the user.
