7/16-14 Flat Head Cap Screw

The 7/16"-14 Flat Head Cap Screw is a heavy-duty, flush-mount fastener designed for applications requiring high clamping strength and a clean, unobtrusive surface finish. With its 82° countersunk flat head and internal hex socket, this screw delivers consistent torque control, tight thread engagement, and a low-profile installation for structural and mechanical assemblies where space or safety is a concern.

Specifications

• Thread Size: 7/16"-14 (Unified National Coarse)

• Head Type: Flat head with 82° countersink and internal hex drive

• Drive Type: Hex socket (Allen)

• Length: Available in standard lengths (typically from 1" to 4")

• Material: Alloy steel; also available in stainless steel, black oxide, or zinc-plated carbon steel

• Finish Options: Black oxide, plain, zinc-plated, or stainless

• Grade: Typically Grade 8 (high-strength alloy steel), or 18-8 / 316 stainless steel for corrosion resistance

Key Features

• Flush-Mounting Head: The 82° countersunk design allows for smooth, flat surface installation in countersunk holes, minimizing interference in assemblies.

• Enhanced Clamping Force: The 7/16" diameter and coarse 14 TPI thread deliver excellent tensile and shear performance in high-load fastening situations.

• Internal Hex Drive: Offers precise torque application and reduced stripping risk, ideal for controlled tightening in structural or recessed environments.

• Durable Finish Options: Available in corrosion-resistant materials and finishes for indoor, outdoor, and industrial environments.

• Standardized Thread Fit: UNC thread form ensures secure compatibility with tapped holes or matched nuts in heavy-duty components.

Typical Applications

The 7/16"-14 Flat Head Cap Screw is ideal for medium-to-heavy-duty mechanical and structural applications, including:

• Machine Guarding and Cover Plates

• Structural Brackets and Framework

• Industrial Panel and Chassis Mounting

• Construction Equipment and Utility Assemblies

• Robotic Frames and Modular Structures

• Agricultural and Material Handling Equipment
