Holo-krome 69430 Low Socket Cap Screw M6x1 40mm

Product Description

The HOLO-KROME 69430 is a low socket cap screw designed for applications where head clearance is limited and a standard socket cap profile will not fit. Manufactured from alloy steel at material grade 10.9, this screw delivers high tensile strength for demanding mechanical assemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection on exposed fastener heads. Thread size is M6x1 (coarse pitch), with a 40 mm length measured under the head. Head height is 4 mm. Drive is a 5 mm hex socket. Licensed machinists, millwrights, and mechanical contractors are the primary installers.

This fastener suits metric assembly work in industrial machinery, tooling fixtures, automotive components, and precision equipment where low-profile head geometry is required. The partially threaded shank allows the unthreaded portion to bear shear loads while the threaded section engages the tapped hole. Typical installations involve tapped through-holes or blind holes in steel, aluminum, or cast components requiring a flush or near-flush fastener surface.

Key Features

• Low socket cap head profile — 4 mm head height — for tight-clearance installations
• Material grade 10.9 alloy steel for high tensile and proof load ratings
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• M6x1 coarse thread pitch conforming to ANSI B1.13M metric fastener standard
• Thread fit class 6G for standard metric tolerance engagement
• 5 mm hex socket drive compatible with standard hex keys and socket bits
• Partially threaded shank to support shear load applications

Compatibility

Designed as an OEM-style metric replacement or service fastener for any application requiring an M6x1 low socket cap screw conforming to ANSI B1.13M.

Installation Notes

Installation is performed by qualified machinists, millwrights, or mechanical technicians using a calibrated 5 mm hex key or hex bit driver. De-energize and lock out all equipment before fastener replacement or assembly work. Verify tapped hole thread class compatibility with the 6G thread fit before installation. Do not exceed the torque capacity appropriate for grade 10.9 M6 fasteners as specified by the applicable assembly drawing or engineering standard.
