Pkmyr Master Gunsmith Hex Head Set

The Pachmayr Master Gunsmith Hex Head Set is a professional-grade screw replacement kit engineered for gunsmiths, armorers, and firearms technicians who need reliable, non-slip alternatives to slotted screws. This specialized kit addresses a critical gap in gunsmithing: sourcing quality hex head screws across multiple sizes and specifications that won't slip under a wrench or socket, preventing marred finish and stripped fasteners on receiver rings, bases, and scope mounts.

The kit includes a comprehensive range of hex head ring and base screws organized in a compartmentalized storage box for quick identification and inventory management. Each screw size is segregated into its own dedicated section, eliminating mix-ups during installation. The package also includes precision tweezers for safe handling of smaller fasteners and a thread size gauge that doubles as a shortening jig—allowing technicians to grind screws to custom lengths when standard sizes don't match a particular application. This multi-function gauge saves both time and material waste on custom jobs.

Gunsmiths and armorer shops benefit most from this kit, particularly those performing scope mounting, sight installation, or receiver work where slip-prone slotted screws create rework and customer dissatisfaction. The hex head design provides positive engagement with standard hex wrenches and sockets, dramatically reducing the risk of fastener damage during installation or removal. Because individual screws are not available separately, the complete kit represents a one-time investment for a shop's core fastening inventory, eliminating repeated supply orders for common sizes.
