Value Collection KP82428 M3x0.50 Button Cap Screw 25-pack

Product Description

The VALUE COLLECTION KP82428 is a fully threaded button socket cap screw in metric M3x0.50 thread size with a 12mm length under head. It features an 18-8 stainless steel construction graded A2, providing corrosion resistance suitable for general-purpose mechanical assemblies. The low-profile button head accepts a 2mm hex socket drive. This screw conforms to ISO 7380 and carries a right-hand thread with a 4G/6G fit class. It is sold in a package of 25 pieces. Maintenance technicians, mechanical assemblers, and field service professionals working with metric hardware will find this fastener suitable for panel mounting, equipment enclosures, and light structural fastening applications.

The KP82428 button socket cap screw is suited for applications where a low-profile head is required to avoid interference with adjacent components. Common install environments include HVAC equipment panels, electrical enclosures, pump housings, and general industrial assemblies that specify metric fasteners. The fully threaded shank provides consistent clamping along the entire engaged length, making it appropriate for thinner material stacks and tapped-hole assemblies. Professionals working to metric standards will recognize this as an ISO 7380-compliant fastener appropriate for light-to-moderate clamping loads.

Key Features

• M3x0.50 metric thread with fully threaded shank for consistent engagement in tapped holes
• 12mm length under head accommodates standard panel and enclosure material stacks
• Low-profile button head reduces protrusion and clearance conflicts in tight assemblies
• 2mm hex socket drive compatible with standard metric hex keys and bit drivers
• 18-8 stainless steel (A2 grade) construction resists corrosion in typical service environments
• Conforms to ISO 7380 fastener standard with 4G/6G thread fit class

Compatibility

Designed as an ISO 7380-compliant metric fastener for use in any tapped M3x0.50 hole requiring a button-head low-profile cap screw with right-hand thread.

Installation Notes

Installation requires a 2mm hex socket driver or L-key. Verify the tapped hole thread class is compatible with a 4G/6G fit before installation. Do not exceed the material shear rating of the base component when torquing stainless steel fasteners, as A2 stainless has lower yield strength than alloy steel grades. Use thread-locking compound only if specified for the assembly, as stainless-to-stainless galling is possible without lubrication.
