Milwaukee 48-22-2181 Sae Folding Hex Key Set 9-piece

Product Description

The Milwaukee Electric Tool Corp 48-22-2181 is a 9-piece SAE folding hex key set designed for trade professionals who need a compact, organized tool for hex fastener work in the field or shop. The keys fold into a single handle unit, reducing bulk and keeping the set intact between uses. Sizes run from 1/16 inches through 3/16 inches, covering the most common SAE hex fastener range found in HVAC equipment, electrical enclosures, plumbing fixtures, and mechanical assemblies. Each key is made of durable steel and color-coded for fast size identification without fumbling through loose keys on a job site.

This set suits any trade that regularly encounters hex-head set screws, cap screws, or adjustment fittings — including HVAC technicians adjusting blower assemblies, electricians working inside panel enclosures, and plumbers servicing valve stems or fixture hardware. The folding form factor is well-suited to tool pouches, service vans, and tight work areas where a full-size T-handle or L-key set would be impractical. The nine included sizes address light-duty fastener work across residential and light commercial service calls.

Key Features

• Nine SAE hex keys in a single folding handle for compact storage
• Size range: 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, and 3/16 inches
• Durable steel construction for repeated service use
• Color-coded keys for fast size identification without a label
• Folding design eliminates loose key storage and reduces loss risk

Compatibility

Designed for use with standard SAE hex socket fasteners across HVAC, plumbing, electrical, and general mechanical applications where hex key sizes from 1/16 to 3/16 inches are required.

Installation Notes

No power source or shutoff is required for hand tool use. Select the correct key size before applying torque to avoid rounding hex socket fasteners. When working inside energized electrical enclosures or active HVAC equipment, follow lockout/tagout procedures per applicable OSHA and NEC requirements before using any hand tools on fasteners. Inspect keys periodically for wear or deformation and replace the set if any key shows signs of rounding or cracking.
