Holo-krome 69488 Low Socket Cap Screw M8x1.25 50mm

Product Description

The HOLO-KROME 69488 is a metric low socket cap screw designed for applications where standard cap screw head height creates clearance problems. Manufactured from grade 10.9 alloy steel with a black oxide finish, this fastener measures M8x1.25 thread size with a 50mm length under head, a 5mm head height, and a 6mm hex socket drive. The coarse thread pitch and 6G thread fit class provide reliable clamping force in precision mechanical assemblies. Licensed tradespeople and maintenance technicians working in tight-tolerance or low-clearance environments rely on this style of fastener where a standard-height cap head would interfere with adjacent components.

The 69488 is suited for mechanical, industrial, and equipment assembly applications where metric fasteners are specified. The low-profile head design is commonly used in machine building, fixture work, and equipment maintenance where standard ISO 4762 socket cap screws exceed available head clearance. Partial threading along the shank allows the fastener to bear shear loads along the unthreaded portion, making it appropriate for locating and clamping applications in metal-to-metal assemblies.

Key Features

• Low socket cap head at 5mm height reduces clearance requirements versus standard cap screws
• Grade 10.9 alloy steel construction provides high tensile and yield strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• 6mm hex socket drive accommodates standard metric Allen keys and socket bits
• Partially threaded shank supports shear load transfer at the joint interface
• Meets ANSI B1.13M and ISO 4762 fastener standards

Compatibility

Designed as a metric replacement or specification fastener for assemblies requiring ISO 4762 low socket cap screws in M8x1.25 coarse thread with 50mm length under head.

Installation Notes

Installation requires a 6mm hex key or socket bit; use a calibrated torque wrench when a specific clamp load is required by the assembly specification. Ensure mating threads are clean and free of debris before installation. Avoid mixing metric and unified thread fasteners in the same assembly. Follow applicable ASME or equipment manufacturer torque guidelines for grade 10.9 metric fasteners.
