1/2 in. x 2‑1/2 in. Hex Bolt, Grade 5 — Model 7200240 (50 Count)
The Model 7200240 Grade 5 hex bolt is a strong, dependable fastening solution designed for construction, mechanical, and maintenance applications that require reliable clamping force and moderate added length. With a 1/2 in. diameter and a 2‑1/2 in. length, this bolt is ideal for securing thicker materials and multi‑layer assemblies while maintaining proper thread engagement and structural integrity.
Manufactured from heat‑treated carbon steel, this Grade 5 hex bolt provides an excellent balance of tensile strength and toughness, making it suitable for applications exposed to moderate load, vibration, and routine mechanical stress. Precision‑rolled threads ensure smooth installation and secure engagement, while the standard hex head allows efficient tightening using commonly available wrenches or sockets. Packaged in a convenient 50‑count box, this fastener supports jobsite efficiency, maintenance operations, and organized inventory management.
