Holo-krome 86035 Button Socket Cap Screw M6x1.00 25mm

Product Description

The HOLO-KROME 86035 is a metric button socket cap screw designed for fastening applications that require a low-profile head and high-strength clamping force. This screw features an M6x1.00 thread with a 25mm length under the head and is driven by a 4mm hex socket. Manufactured from Grade 12.9 alloy steel with a black oxide finish, it delivers a minimum hardness of 38 HRC. The fully threaded shank and right-hand thread direction make it a standard choice for precision mechanical assemblies. Licensed tradespeople and industrial maintenance techs use this fastener where a standard hex cap screw head would interfere with mating components.

The 86035 is suited for use in machine tool fixtures, hydraulic components, structural brackets, and general mechanical assemblies where a low-profile button head is required. The black oxide finish provides moderate corrosion resistance in controlled environments. Its metric thread standard and ANSI/ASME B18.3 and ASTM F835 conformance make it a reliable fit for both OEM manufacturing and field maintenance applications. The 4G and 6G thread fit classes allow for consistent engagement across standard metric tapped holes.

Key Features

• M6x1.00 thread with 25mm length under head for precise fitment in metric assemblies
• Grade 12.9 alloy steel construction rated at 38 HRC minimum hardness for high-load applications
• 4mm hex socket drive for use with standard hex keys and socket drivers
• Black oxide finish for a clean appearance and moderate corrosion resistance
• Fully threaded shank in a right-hand direction for standard metric tapped holes
• Conforms to ANSI/ASME B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style replacement or production fastener for metric mechanical assemblies requiring a button head cap screw with an M6x1.00 thread profile and 4G or 6G thread fit class.

Installation Notes

Installation is performed with a 4mm hex key or hex socket driver. Verify that the tapped hole depth and thread class are compatible before installation. Follow torque values specified by the equipment manufacturer or applicable ANSI fastener standards for Grade 12.9 hardware. Do not mix metric and inch-series fasteners in the same assembly.
