3/4 in. x 5 in. Hex Cap Screw, Grade 5 — Model 200438 (20 Count)

The Model 200438 Grade 5 hex cap screw is a heavy‑duty, extended‑length fastener designed for structural and mechanical applications that require substantial strength, deep reach, and dependable clamping force. With a large 3/4 in. diameter and a 5 in. length, this fastener is well suited for thick materials, multi‑layer assemblies, and load‑bearing connections where durability and controlled flexibility are essential.

Manufactured from heat‑treated carbon steel, this Grade 5 hex cap screw delivers a proven balance of tensile strength and toughness, allowing it to perform reliably under sustained load, vibration, and everyday mechanical stress. Precision‑rolled threads ensure smooth installation and secure thread engagement, while the hex cap head provides strong tool contact for efficient tightening using standard wrenches or sockets. Packaged in a 20‑count box, this product is ideal for project‑based work, equipment installation, and professional jobsite use.
