Value Collection FHS1XX1240-025BX M12x1.75 Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX1240-025BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head driven by an 8 mm hex socket and is machined from 316 austenitic stainless steel to Grade A4, providing strong resistance to corrosion in wet, marine, and chemical-exposure environments. The screw has an overall length of 40 mm with a partial thread length of 30 mm and a Thread Fit Class of 6G, conforming to DIN 7991. Tradespeople and industrial maintenance professionals use this fastener where a protruding head would interfere with mating surfaces or moving parts.

This flat socket cap screw is suited for mechanical assemblies, structural connections, and equipment fabrication in marine, food processing, pharmaceutical, and coastal construction settings where stainless steel fasteners are required. Its metric M12x1.75 thread size and DIN 7991 standard make it a direct fit for European-specification machinery and metric-dimensioned structural components. The plain finish leaves the stainless alloy exposed, which is appropriate for environments where coatings may degrade or contaminate the application.

Key Features

• 316 austenitic stainless steel, Material Grade A4 -- high corrosion resistance in chloride and marine environments
• 90-degree flat head profile for flush or countersunk installation
• 8 mm hex socket drive for standard Allen key or hex bit tools
• Partial threading with 30 mm thread length on a 40 mm overall length
• Thread Fit Class 6G per DIN 7991 metric fastener standard
• Plain finish -- no coating or plating that could affect dimensional tolerances

Compatibility

Designed for use in metric-threaded M12x1.75 countersunk or flush-mount applications conforming to DIN 7991 specifications.

Installation Notes

This fastener is installed by machinists, millwrights, and maintenance technicians using an 8 mm hex key or socket bit. Countersink the mating hole to 90 degrees to achieve full head seating. Power down and de-energize any equipment before fastener replacement or assembly work. Do not mix stainless steel fasteners with dissimilar metals in corrosive environments without evaluating galvanic compatibility.
