Value Collection FHS1XX1280-025BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX1280-025BX is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastener. The 90-degree flat head seats flush with or below the mating surface, eliminating protrusion where clearance is critical. Driven by an 8.00 mm hex socket, the screw is manufactured from 316 austenitic stainless steel to Material Grade A4, providing strong resistance to corrosion in wet, marine, and chemically active environments. Overall length is 80.00 mm with a thread length of 30.00 mm, making it partially threaded. Thread size is M12x1.75 with a 6G thread fit class per DIN 7991.

This fastener is suited for mechanical assemblies, structural connections, and equipment fabrication in industries where corrosion resistance is a priority. Typical applications include marine hardware, food-processing equipment, chemical handling systems, and outdoor structural installations. The plain finish means no additional coating is applied, keeping dimensions predictable and surface treatment decisions with the installer or engineer. Professional machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

Key Features

• 90-degree flat head seats flush with the mating surface for low-profile clearance
• 8.00 mm hex socket drive for precise torque application with standard Allen tooling
• 316 austenitic stainless steel, Material Grade A4, for superior corrosion resistance
• M12x1.75 thread size, Thread Fit Class 6G, conforming to DIN 7991
• Partially threaded shank — 30.00 mm thread length out of 80.00 mm overall length
• Plain finish maintains true dimensional tolerances with no coating buildup

Compatibility

Designed as a DIN 7991 metric flat socket cap screw for use in M12x1.75 tapped holes requiring a flush or countersunk head fastener in corrosion-resistant stainless steel assemblies.

Installation Notes

Installation requires a clean, properly dimensioned 90-degree countersunk hole to achieve full head seating. Use a calibrated torque wrench with the appropriate 8.00 mm hex bit to avoid galling, which is common with stainless steel fasteners — applying an anti-gall lubricant or anti-seize compound is standard practice. Power down or de-energize any equipment before fastener work on live assemblies. Verify thread engagement depth meets the requirements of the applicable structural or mechanical standard for the installation.
