Holo-krome 86007 Button Socket Cap Screw M4x0.70 8mm

Product Description

The HOLO-KROME 86007 is a metric button socket cap screw designed for applications requiring a low-profile head and high clamping strength. Sized M4x0.70 with an 8mm length under the head, this fully threaded fastener is manufactured from Grade 12.9 alloy steel, making it one of the highest-strength classes available in metric fasteners. The black oxide finish provides moderate corrosion resistance and reduces surface reflectivity. The hex socket drive measures 2.55mm and accepts a standard hex key. Licensed tradespeople and mechanical assemblers use this screw where a flush or recessed button head is required over a standard cap head profile.

This screw is suited for machine assembly, sheet metal fabrication, and precision equipment where a low-profile head reduces interference with adjacent components. The right-hand thread and 4G thread fit class make it compatible with standard metric tapped holes. It conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards, which are commonly specified in industrial and OEM assembly applications. Minimum order quantity is 100 pieces per order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Button head profile with 7.6mm head diameter and 2.2mm head height for low-profile installations
• Black oxide finish for moderate corrosion resistance and reduced reflectivity
• 2.55mm hex socket drive compatible with standard metric hex keys
• Fully threaded M4x0.70 metric thread, right-hand direction, 4G and 6G thread fit class
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard metric replacement or OEM-style fastener for any application requiring an M4x0.70 button socket cap screw in Grade 12.9 alloy steel with a 4G or 6G thread fit class.

Installation Notes

Installation requires a 2.55mm hex key or hex socket bit. Ensure the receiving tapped hole is clean and free of debris before driving. Do not exceed the rated torque capacity of the M4 thread engagement depth. Power down or de-energize any equipment before performing fastener service on electrical or mechanical assemblies.
