1/4-20 x 4-1/2 Coarse Hex Cap - Grade 5 Box/100

Overview

The 1/4-20 x 4-1/2 Coarse Hex Cap Screw (00265) is designed for general fastening applications requiring a wrench-driven hexagonal head fastener. Manufactured by Midwest Fastener Corp., this Grade 5 hex cap screw is sold in a box of 100, making it suitable for both production and maintenance applications where consistent, reliable fastening is required.

Technical Features

• Grade 5 Strength Rating: Meets the mechanical requirements of SAE Grade 5, providing medium-high tensile strength suitable for structural and load-bearing fastening tasks.
• 1/4-20 Coarse Thread (UNC): Coarse thread pitch engages faster during installation and offers greater resistance to cross-threading compared to fine thread, improving assembly efficiency.
• 4-1/2 in. Length: Extended length accommodates thicker material stacks or deep through-bolt applications where shorter fasteners would be insufficient.
• Hexagonal Head Design: Engineered to be driven by a standard open-end, box, or socket wrench, enabling high torque application and secure, repeatable tightening.
• Box of 100: Bulk packaging reduces per-unit cost and ensures an adequate supply for production runs, maintenance kits, or job-site inventories.

Applications

• General structural assembly and fabrication where Grade 5 tensile strength is specified.
• Mechanical and equipment assembly requiring wrench-driven, externally threaded fasteners.
• Through-bolt applications in wood, metal, or composite materials using the 4-1/2 in. length.
• Maintenance and repair operations calling for a standard 1/4-20 UNC coarse thread specification.
