Hexagon Socket Head Cap Screw – Overall Description

A Hexalobular socket oil plug screw (SHCS), commonly referred to as an Allen screw または socket head screw, is a high-strength fastener designed for precision applications where a flush or low-profile head is required. It features a cylindrical head with an internal hexagonal drive (socket) that requires a hex key (Allen wrench) or a hex bit for installation.

Key Characteristics:

1. Head Design:

   • Cylindrical shape with a flat top and chamfered edges.

   • Provides a low-profile and smooth surface, reducing interference in tight spaces.

2. Drive Type:

   • Internal hexagon (hex socket) for secure engagement with an Allen key または hex driver.

   • Prevents cam-out (slipping) compared to Phillips or slotted drives.

3. Thread Configuration:

   • Available in fully threaded または partially threaded (with an unthreaded shoulder) variants.

   • Threads conform to metric (ISO) または imperial (UNC/UNF) standards.

4. Materials & Finishes:

   • Common Materials:

     • Carbon steel (Grade 8.8, 10.9, 12.9)

     • Stainless steel (A2/A4 – corrosion-resistant)

     • Titanium (lightweight, high strength)

     • Alloy steel (heat-treated for extreme conditions)

     • Hexalobular socket oil plug screw

   • Common Finishes:

     • Black oxide (mild corrosion resistance)

     • Zinc plating (enhanced corrosion protection)

     • Anodized (for aluminum screws)

     • Plain/uncoated (for machining applications)

一般的な用途：

• Machinery & Automotive (engine parts, gearboxes, fixtures)

• Aerospace & Defense (high-stress assemblies)

• Electronics & Robotics (compact, precision devices)

• Medical Equipment (sterile, high-reliability fastening)

• DIY & Furniture (discreet, strong fastening)

Sizing & Dimensions:

• Metric Sizes: M2, M3, M4, M5, M6, M8, M10, M12, etc.

• Imperial Sizes: #4-40, #6-32, #8-32, 1/4″-20, 5/16″-18, 3/8″-16, etc.

• Lengths: Vary from a few millimeters to several inches.

インストールのヒント

• Use a properly sized Allen key to avoid rounding the socket.

• Apply thread-locking compound (e.g., Loctite) for vibration resistance.

• Follow recommended torque values to prevent over-tightening.
