In the hand tool industry, safety, reliability, and user comfort are non-negotiable. At Principal Manufacturing Corporation, we deliver high-volume metal stamping, precision-machined components, and overmolded features designed to meet demanding performance, ergonomic, and durability standards.

With in-house tooling, integrated production, and a flexible approach to part design and scaling, we help OEMs and tool manufacturers accelerate speed to market without compromising strength or quality.

Built for Strength, Safety, and Scalability

We support a wide range of hand tool components, including:

  • Handles and grips with overmolded surfaces
  • Mounting and structural brackets
  • Levers, triggers, and actuators
  • Cutting, fastening, or striking elements
  • Stamped metal inserts and housing components
  • Precision mating features requiring tight tolerances

Whether you’re producing thousands of units or shifting to a new product line, our processes are built to flex with your needs.

Complete In-House Capabilities

Our vertically integrated model brings together:

  • Fine blanking for fully sheared edges and repeatable geometries
  • High-volume metal stamping with progressive dies and compound tooling
  • CNC machining for tight-tolerance shafts, bores, or slots
  • Plastic overmolding for enhanced grip, protection, and aesthetics
  • Custom stamped metal components from carbon steel, stainless, brass, copper, and more
  • Secondary operations like orbital riveting, tapping, and automated assembly

We also produce sheet metal stampings and hybrid components that combine metal and plastic for a streamlined final assembly.

Certified High Quality Metal Stamping for Critical Applications

Every part we produce is backed by rigorous quality control. Principal is certified to IATF 16949:2016 and ISO 14001:2015, and we maintain ITAR compliance for regulated applications. Our inspection lab verifies form, fit, and finish — ensuring that every component performs as expected, every time.
