Paramount PAR14138 30-piece Combo Hex Key Set

Product Description

The PARAMOUNT PAR14138 is a 30-piece combination hex key set that covers inch, metric, and Torx drive sizes in a single kit. It includes both L-wrench and fold-up style handles, giving technicians the flexibility to apply torque in tight spaces or drive fasteners quickly with the fold-up format. The hex size range runs from 0.050 to 3/8 inches on the inch side and 1.5 to 10 mm on the metric side, with Torx coverage from T9 to T40. All keys are steel construction. The set ships in a blister pack and weighs 2.2 pounds.

This set is suited for HVAC, electrical, plumbing, and general mechanical service work where a wide range of fastener drives are encountered on a single job. The combination of L-wrench and fold-up formats in one kit reduces the need to carry separate tool sets. The Torx range makes it practical for equipment that uses tamper-resistant or OEM fasteners common in modern HVAC and refrigeration units. It is appropriate for both shop and field use.

Installation Notes

Select the correct key size before applying torque to avoid rounding fastener heads. Always power down or isolate equipment before using hand tools on electrical or mechanical assemblies. L-wrench keys provide greater torque leverage; use the fold-up format for speed in accessible locations. Inspect keys for wear or deformation before use and replace any damaged pieces to prevent fastener damage.
