MGPTC-R8-20G, Huck Magna-GR Lockbolts, 0.250 Inch Diameter, (0.312-1.250 Inch GR), Stainless Encapsulated HD, HD

Description

Product Overview

The Huck MGPTC-R8-20G lockbolts are a premium solution for demanding industrial fastening needs. Constructed from high-grade stainless steel, each bolt features an encapsulated HD (Heavy Duty) body that resists corrosion, wear, and the harshest environmental conditions. The 0.250 inch diameter provides a solid core that transfers load efficiently, while the engineered grip range of 0.312 to 1.250 inches allows a single bolt to replace up to four traditional HuckBolts, simplifying inventory and reducing part counts. Precision machining ensures uniform installed values, delivering repeatable torque and preload performance across every installation. The lockbolt design incorporates a self‑locking mechanism that eliminates the need for additional washers or locking compounds, delivering a clean, reliable connection that resists loosening under vibration and shock. With a weight of just 14.88 ounces per unit, the bolts are easy to handle yet robust enough for heavy‑duty applications.

Usage

These lockbolts excel in a wide range of industrial settings, from automotive assembly lines to heavy machinery maintenance, aerospace component fastening, and marine equipment installations. Their vibration‑resistant design makes them ideal for rotating equipment such as gearboxes, pumps, and compressors, where traditional fasteners often fail. The broad grip range accommodates varying material thicknesses, allowing technicians to secure thin sheet metal as well as thick structural components without changing hardware. Because the bolts are stainless, they are suitable for outdoor applications, chemical processing plants, and any environment where exposure to moisture or corrosive agents is a concern. The 25‑piece packaging ensures that large‑scale projects have sufficient inventory on hand, reducing downtime caused by part shortages.
