Wheeler 4001003 Professional 100-Piece Black Screwdriver Set

The Wheeler Professional 100-Piece Black Screwdriver Set is a gunsmith's workhorse—a comprehensive bit collection built to handle the diverse fasteners found across modern and vintage firearms without marring or damaging screw slots. Whether you're performing maintenance on a hunting rifle, tuning a competition gun, or restoring a classic revolver, this set puts the right bit in your hand for nearly every job that lands on your bench.

What makes this screwdriver set stand out is the engineering behind the bit selection. Wheeler's design process involved measuring actual firearm screws across more than a hundred different rifle, shotgun, and handgun models—from common platforms like the Remington 700 to specialty pieces like Browning over-unders and Colt Single Actions. The result is a 100-piece collection that prioritizes real-world relevance over generic filler. Each bit is manufactured from S2 tool steel and hardened to 56–58 Rockwell C, giving them the durability and precision needed to seat properly without slipping or deforming under pressure.

This set belongs on any reloader's, gunsmith's, or serious maintenance enthusiast's bench. The black finish reduces glare under work lights, and the comprehensive range means you'll spend less time hunting for the right bit and more time getting the work done right the first time.

Frequently Asked Questions

What firearms does this screwdriver set work on?

The 100-piece assortment was engineered by measuring screw slots on over 100 modern and antique firearms, including rifles (Remington 700), shotguns (Browning Superposed), revolvers (Smith & Wesson), and single-action pistols (Colt). The breadth of included bits covers most hunting rifles, competition guns, and vintage firearms you're likely to encounter.

Why does bit material and hardness matter for gunsmithing?

Firearm screws often have tight tolerances and soft metal slots that can be easily damaged by the wrong tool or inadequate hardness. Wheeler's S2 tool steel bits, hardened to 56–58 Rockwell C, are engineered to seat firmly without slipping or causing the deformation and scarring that ruins both the aesthetic and function of a gun.

Is this set suitable for gun maintenance and detail work?

Yes. This set is designed for both gunsmithing bench work and field maintenance, making it useful whether you're performing routine upkeep, installing aftermarket components, or deeper repair and restoration work.
