Product Description:

These 3/8-16 x 3-1/2 Grade 5 Carriage Bolts are crafted from durable Grade 5 steel, offering reliable strength and long-lasting performance for demanding applications. Featuring a large, domed head, they provide a clean finished appearance and maximum holding power in wood. The head stamping allows for easy class and grade identification even after installation, ensuring confidence in quality and specification.

Designed with precise threading, these bolts ensure smooth engagement and strong holding power, keeping components securely connected under stress. The zinc finish offers moderate corrosion resistance, making them suitable for many indoor and outdoor projects; however, they are not recommended for chemically treated wood—hot-dipped galvanized fasteners should be used in those cases.

Ideal for construction, woodworking, and general fastening needs, these carriage bolts are a dependable choice for professionals and DIY enthusiasts alike. Their combination of strength, appearance, and ease of use makes them a versatile fastener for a wide range of industrial and residential applications.
