Proto J1200SPL Spline Combination Wrench Set 15 Pc

Product Description

The PROTO J1200SPL is a 15-piece spline combination wrench set designed for professional trade use in mechanical, HVAC, and industrial service applications. Each wrench features a chrome-plated finish for corrosion resistance and a 15-degree head offset angle that improves clearance in tight spaces. The 12-point box end engages fasteners with reduced slip risk, making the set well suited for high-torque applications on hex and spline fasteners. The full set stores in an included tool roll for organized transport to job sites. At 6.63 pounds, the set offers substantial tool steel mass across 15 sizes ranging from 1/4 inch through 1 inch.

This wrench set is built for inch-measurement fasteners and covers a wide range of common sizes used in HVAC equipment, plumbing systems, electrical panel work, and general mechanical service. The 15-degree offset box end allows access to recessed fasteners in equipment cabinets, compressor housings, and piping assemblies. Licensed tradespeople and experienced DIYers working on equipment with spline or hex fastener heads will find the full size range sufficient for most service calls. The tool roll container keeps all 15 wrenches organized and reduces loss on multi-point jobs.

Installation Notes

Combination wrenches are typically used by HVAC technicians, plumbers, and electricians during equipment installation and service. Always de-energize electrical systems and shut off gas or water supply before loosening fasteners on live systems. Select the correct wrench size for a snug fit on the fastener to avoid rounding. Inspect chrome finish periodically for chips or corrosion that could indicate tool wear.
