5/8 in. x 6 in. Hex Cap Screw, Grade 5 — Model 200381 (25 Count)

The Model 200381 Grade 5 hex cap screw is a strong, extended‑length fastening solution designed for structural and mechanical applications where deep reach, dependable clamping force, and long‑term durability are required. With a substantial 5/8 in. diameter and a long 6 in. length, this fastener is ideal for thick materials, stacked assemblies, and heavy‑duty connections that demand secure engagement across multiple components.

Manufactured from heat‑treated carbon steel, this Grade 5 hex cap screw delivers an optimal balance of tensile strength and toughness, allowing it to perform reliably under load, vibration, and everyday stress without excessive brittleness. Precision‑rolled threads provide smooth installation and consistent holding power, while the hex cap head allows efficient tightening using standard wrenches or sockets. Packaged in a convenient 25‑count box, this product is well suited for jobsite, maintenance, and fabrication use.
