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

Overview

The 1/4-20 x 5 Coarse Hex Cap Screw (00266) is designed for general-purpose fastening applications requiring a wrench-driven hexagonal head fastener. Manufactured by Midwest Fastener Corp., this hex cap screw is sold in a box of 100 units, making it suitable for production, maintenance, and construction environments where consistent fastener supply is essential.

Technical Specifications

Technical Features

• Grade 5 Construction: Meets SAE Grade 5 strength requirements, providing greater tensile strength than Grade 2 fasteners and making these screws suitable for medium-duty structural and mechanical assemblies.
• 1/4-20 UNC Coarse Thread: The unified coarse thread profile allows for faster assembly and disassembly and offers improved resistance to cross-threading compared to fine-thread variants.
• 5-Inch Length: The extended 5-inch shank accommodates thicker material stacks or applications requiring significant clamping depth.
• Hexagonal Head Design: The six-sided head is engineered to be driven by a standard open-end, box, or socket wrench, enabling high torque application without slippage.
• Box Quantity of 100: Bulk packaging reduces per-unit cost and ensures an adequate supply for repetitive fastening tasks on job sites or in production environments.

Applications

• General structural assembly where medium-strength, wrench-driven fasteners are specified
• Mechanical and equipment fabrication requiring 1/4-20 UNC threaded connections
• Construction and maintenance tasks involving thick material sections suited to a 5-inch fastener length
• Production environments benefiting from bulk fastener availability
