Parallel Drive Shaft Key 140PCS SAE Stainless Steel Round End Set

Description

Product Overview

The 140PCS Parallel Drive Shaft Key assortment is engineered for precision, durability, and versatility in demanding power‑transmission environments. Each key is forged from high‑grade stainless steel, then treated with a robust powder‑coated finish that resists corrosion, wear, and chemical exposure, extending service life even under continuous operation. The round‑ended design provides smooth engagement with keyed shafts, minimizing stress concentrations and reducing the risk of premature failure. Dimensions are carefully controlled to meet SAE standards, ensuring compatibility with a wide range of shaft diameters and keyways commonly found in industrial machinery, automotive applications, and heavy‑duty equipment. The set includes a comprehensive range of sizes, from small‑diameter keys for delicate instrumentation to larger keys for high‑torque gearboxes, allowing users to stock a single inventory that addresses multiple specifications. Product dimensions of the packaging are 5.91 × 2.36 × 1.38 inches, and the total weight of 14.9 ounces makes handling and storage straightforward. The inclusion of a detailed size chart and clear labeling further simplifies selection, while the powder‑coated finish eliminates the need for additional protective treatments. This key stock is designed to function as a fastener, providing a secure mechanical lock that transmits torque efficiently and reliably across a variety of mechanical assemblies.

Usage

These parallel drive shaft keys are ideal for a broad spectrum of industrial and scientific applications where precise torque transmission is critical. Typical usage scenarios include assembly of gearboxes, coupling installations, motor shafts, pump drives, and conveyor systems where a keyed connection prevents slippage under load. The stainless‑steel construction makes the keys suitable for environments with exposure to moisture, chemicals, or temperature fluctuations, such as food‑processing plants, chemical processing facilities, and outdoor equipment. Maintenance technicians appreciate the ease of installation: the round‑ended profile slides smoothly into the keyway, and the powder‑coated surface reduces the need for lubrication or additional protective measures. Because the set covers a full range of standard SAE dimensions, engineers can select the exact size required for each shaft without ordering multiple separate kits, streamlining procurement and reducing lead times. The keys are also compatible with CNC‑machined components, allowing seamless integration into modern manufacturing workflows. Whether retrofitting legacy equipment or outfitting new machinery, the 140‑piece assortment provides the flexibility to meet diverse design requirements while maintaining consistent performance.
