Keystone Fastening Technologies
Fasteners
Company Overview
Keystone Fastening is a recognized leader in fastening technologies, offering an extensive range of stud welding systems, weld studs, automation solutions, and specialty fasteners. The company emphasizes precision engineering, durability, and consistent performance across its product lines. Keystone's proprietary Microprocessor and Current Regulation Technology are central to achieving exceptional weld quality and unparalleled consistency in various industrial applications.
Products and Services
Keystone Fastening provides a comprehensive product portfolio, encompassing both Capacitor Discharge (CD) and Drawn Arc (DA) stud welding equipment. Their CD systems, like the 308 and 318 Series, are available in analog and digital configurations, while DA systems such as the DA-280 D and DA-300i Inverter are engineered for long-term durability with digital interfaces. The company offers a wide array of weld studs, including threaded, internal thread, paint groove, flanged, and non-flanged options in mild steel, stainless steel, and aluminum. Specialty studs, such as headed concrete anchors and refractory anchors, are also available, alongside custom designs and military specifications. A full range of accessories, compatible with major brands, complements their welding solutions. Stud welder rental services are also offered.Beyond welding, Keystone supplies high-quality drilling and tapping systems, including JOYTAP, SNIPER, and DRILLTRONIC. These systems feature brushless servo motors for precise speed control and extensive tapping capacities (e.g., JT Series up to 1-3/8' (m36)). Often integrated with VOLUMEC articulating arms, they provide flexibility for various part manipulation tasks. Keystone also specializes in semi and fully automated stud welding solutions and custom CNC production equipment.
Technology and Quality Assurance
Keystone's welding processes are designed for efficiency and reliability. The CD process ensures rapid welds (approx. 0.004 seconds), suitable for thin gauge materials without reverse-side marring. The Drawn Arc process creates robust fusion welds, often stronger than the stud itself, capable of joining dissimilar metals with ceramic ferrules. All Keystone systems incorporate dual grounds for optimal results. The company maintains stringent quality control throughout production, adhering to directives like European REACH and RoHS. A dedicated Prototyping Lab offers application analysis, 3D modeling, and engineering support for custom fastener solutions, leveraging advanced manufacturing capabilities.
