Holo-krome 86027 Button Cap Screw M6x1.00 10mm Grade 12.9

Product Description

The HOLO-KROME 86027 is a metric button socket cap screw designed for applications requiring a low-profile head and high clamping strength. It features an M6x1.00 thread with a 10mm length under head and is driven by a 4mm hex socket. Manufactured from Grade 12.9 alloy steel with a black oxide finish, this fastener delivers a hardness of 38 HRC and strong corrosion resistance in a compact form factor. The button head profile reduces snag points and distributes load across a wider bearing surface than a standard socket head. Licensed tradespeople and precision assembly technicians specify this screw where flush or semi-flush fastening is required in tight clearance conditions.

This button socket cap screw is suited for mechanical assemblies, machine guards, panels, and structural joints where a low-profile fastener head is specified. The black oxide finish provides moderate corrosion protection and reduces light reflection, making it appropriate for both interior machinery and equipment housings. It conforms to ANSI/ASME B18.3 and ASTM F835 standards, which are commonly referenced in industrial fabrication, OEM equipment assembly, and maintenance-repair operations. The fully threaded shank allows consistent engagement across the full length of the fastener in through-hole and tapped applications.

Key Features

• Grade 12.9 alloy steel construction with 38 HRC hardness for high-strength fastening
• Button head profile provides low-profile, snag-resistant seating with wide load distribution
• 4mm hex socket drive for precise torque application in tight spaces
• Black oxide finish for moderate corrosion resistance and reduced reflectivity
• Fully threaded shank with M6x1.00 metric thread and right-hand thread direction
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard metric button socket cap screw per ANSI/ASME B18.3 and ASTM F835, compatible with M6x1.00 tapped holes and through-holes using standard metric thread class 4G or 6G fits.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician using a calibrated 4mm hex key or socket driver. Verify that mating tapped holes conform to M6x1.00 metric thread specifications before installation. Do not exceed recommended torque values for Grade 12.9 fasteners as specified by the applicable engineering standard or equipment manufacturer documentation. This fastener is not intended for use in applications requiring a fully non-ferrous or stainless material where black oxide finish is insufficient for the service environment.
