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

Overview

The 1/4-20 x 1-1/2 Coarse Hex Cap Screw – Grade 5, Box/100 (00256) is designed for general fastening applications requiring a medium-strength, wrench-driven hex cap screw.

Technical Features

• Grade 5 Strength Rating: Meets medium-strength fastener standards, making these screws suitable for structural and mechanical assemblies where higher load capacity is required compared to Grade 2 fasteners.
• 1/4-20 Coarse Thread Pattern: Coarse threading provides faster engagement and greater resistance to cross-threading, improving installation efficiency in softer materials and higher-vibration environments.
• Hexagonal Head Design: The six-sided head accepts standard open-end, box, or socket wrenches, allowing for high-torque driving and secure tightening without tool slippage.
• 1-1/2 in. Length: Provides adequate thread engagement depth for a wide range of material thicknesses commonly encountered in general construction and mechanical assembly.
• Box Quantity of 100: Bulk packaging reduces per-unit cost and ensures an adequate supply for project-scale or repeated fastening tasks.

Applications

• General construction and structural assembly where a wrench-driven, medium-strength fastener is specified.
• Mechanical and equipment assembly requiring coarse-thread engagement for reliable clamping force.
• Fabrication and maintenance tasks using standard 1/4-20 threaded components or tapped holes.
• Any application calling for a Grade 5 hex cap screw in a 1/4 in. diameter, 1-1/2 in. length configuration.
