Value Collection FHS1XX1290-025BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX1290-025BX is a metric flat socket cap screw designed for applications requiring a low-profile, flush-mounted fastener with high corrosion resistance. This screw features an M12x1.75 thread size, an 8 millimeter hex socket drive, and a 90-degree flat head profile that sits flush with or below the mating surface when fully seated. The overall length is 90 millimeters, and the shank is partially threaded. Constructed from 316 austenitic stainless steel to Grade A4, it offers strong resistance to corrosion in wet, marine, and chemically aggressive environments. Typically installed by mechanical contractors, millwrights, or industrial maintenance technicians.

This flat socket cap screw is suited for use in industrial machinery, marine hardware, food-processing equipment, chemical processing assemblies, and structural fabrication where corrosion resistance and a flush fastener profile are required. The Grade A4 316 stainless steel designation makes it appropriate for chloride-exposed environments such as coastal installations or washdown areas. The hex socket drive allows installation with a standard Allen key or hex bit driver in confined clearances where a conventional wrench cannot reach.

Key Features

• M12x1.75 metric thread — standard coarse pitch for broad hardware compatibility
• 90-degree flat head profile seats flush with or recessed into the mating surface
• 8 millimeter hex socket drive for use with Allen keys or hex bit drivers
• Partially threaded shank for strong clamping in through-bolt applications
• 316 austenitic stainless steel, Grade A4 — rated for marine and corrosive-environment use
• 90 millimeter overall length suitable for moderate material stack thicknesses

Compatibility

Designed as a metric flat socket cap screw for use wherever an M12x1.75 coarse-thread, 90-degree flat-head fastener with a hex socket drive is specified.

Installation Notes

Installation should be performed using a calibrated torque wrench with the appropriate 8 millimeter hex bit to avoid over-torquing the stainless steel threads, which are susceptible to galling. Apply an anti-seize compound rated for stainless-to-stainless contact before threading to reduce the risk of thread seizure. Ensure mating holes are clean, properly tapped to M12x1.75, and free of debris before installation. Follow applicable mechanical codes and equipment manufacturer specifications for fastener torque requirements.
