1/4-Inch Drive Phillips PH4 Socket Bit, Cr-V Steel

Brief Overview

This PH4 Phillips socket bit is purpose-built for precision work with #4 Phillips fasteners in confined spaces and delicate assembly tasks. The 1/4-inch drive format integrates seamlessly with standard quarter-inch ratchets and power tools, making it an essential addition to any shop stocking smaller Phillips socket sizes through the full range. The chromium-vanadium steel construction provides the hardness and wear resistance required for production environments where fastener stripping must be minimized.

Key Features

• PH4 Cross Profile: Four-lobed Phillips tip engineered to center precisely on #4 Phillips head fasteners
• 1/4-Inch Drive: Compatible with all standard quarter-inch drive ratchets, torque wrenches, and power tools
• Cr-V Steel Construction: Chromium-vanadium alloy resists deformation and maintains tip geometry through thousands of cycles
• Knurled Grip Band: Textured middle section provides tactile feedback and prevents hand slippage during manual operation
• Chamfered Entry: Slightly beveled socket opening reduces driving errors and fastener misalignment
• Two-Tone Finish: Bright chrome-plated socket body with hardened grey tool steel bit for visual contrast and corrosion resistance

Business Advantages for Resellers

This socket bit targets a specific but steady demand segment:

• Production Assembly Lines: Electronics, precision machinery, and medical device manufacturers require PH4 bits in volume—this size moves consistently in industrial settings
• Margin-Friendly: Single-piece socket bits command better margins than boxed sets, allowing resellers to optimize inventory mix
• Complement Existing Stock: Customers already purchasing other Phillips drive sizes will naturally add PH4 to their kits—easy upsell opportunity
• Low Return Rate: Cr-V construction minimizes tip wear complaints, protecting your reputation and reducing warranty exposure
• Bulk Order Friendly: Minimal packaging, high-density shipping, and consistent demand make this ideal for contract orders with manufacturers

Application Context

The PH4 Phillips bit is the workhorse for mid-sized fasteners in precision assembly. Common applications include:

• Electronics Manufacturing: Assembly of computer peripherals, networking equipment, and consumer electronics
• Precision Machinery: Drive fasteners on control panels, instrument clusters, and calibrated assemblies
• Medical Device Assembly: Reliable fastening in sterile and semi-sterile environments
• Automotive Electronics: Dashboard clusters, control modules, and sensor mounting

This is not a heavy-duty impact driver—it's engineered for controlled torque application where fastener integrity matters. Position this to shops servicing precision assembly rather than general mechanics.

Why Stock This Size

The PH4 Phillips socket bit represents reliability at a specific fastener scale. Its chromium-vanadium construction ensures consistent performance across high-volume production runs, while the compact 37mm length works in tight quarters where larger drivers won't fit. For distributors serving manufacturing and assembly sectors, this single size can anchor a complete Phillips socket line.
