Value Collection BHS7X04030-050BX M4x0.7 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION BHS7X04030-050BX is a partially threaded button socket cap screw designed for metric fastening applications requiring a low-profile head. Manufactured from A2 (18-8) stainless steel with a bright uncoated finish, this fastener delivers corrosion resistance suited to general industrial, marine-adjacent, and equipment assembly environments. The M4x0.7 thread pitch and 2.50 mm hex socket drive allow precise installation with a standard hex key or ball-end driver. Conforming to ANSI/ASME B18.3.4M and ISO 7380, it meets internationally recognized dimensional and mechanical standards. Sold in a minimum order quantity of 50 pieces per box.

This screw is used wherever a button-head profile is needed to reduce snag risk or clear adjacent components in tight assemblies. Typical applications include light machinery frames, electronic enclosures, panel mounting, and general fabrication work. The 30 mm length under head and M4x0.7 thread make it a common choice in metric machine assembly for both OEM production and field repair tasks. The right-hand thread direction and 6G thread fit class ensure standard engagement with metric tapped holes and nuts across a wide range of materials.

Key Features

• M4x0.7 metric thread with 6G thread fit class for standard metric tapped hole engagement
• 30 mm length under head, partially threaded, for versatile fastening depth
• A2 (18-8) stainless steel construction for corrosion resistance without a coating
• 2.50 mm hex socket (Allen) drive for controlled torque application in tight spaces
• Button head profile reduces protrusion and snag risk in assembled equipment
• Meets ANSI/ASME B18.3.4M and ISO 7380 dimensional standards

Compatibility

Designed as an OEM-style and general-purpose replacement fastener for metric M4x0.7 threaded applications conforming to ISO 7380 button socket cap screw specifications.

Installation Notes

Installation is typically performed by machinists, assemblers, or maintenance technicians using a 2.50 mm hex key or ball-end driver. Ensure the mating tapped hole is clean and free of debris before driving. Do not exceed the torque rating appropriate for A2 stainless steel M4 fasteners as specified by the equipment manufacturer. Avoid cross-threading by starting the screw by hand and confirming thread engagement before applying drive torque.
