Value Collection FHS1X0890-010BX M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0890-010BX is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head with a hex socket drive and is manufactured from 18-8 austenitic grade A2 stainless steel, offering solid corrosion resistance in moderate service environments. The screw carries an M8x1.25 thread size and measures 90 millimeters in overall length. It is partially threaded, which helps maintain clamping load across unthreaded shank sections. This fastener follows the DIN 7991 standard and is suited for mechanical assembly, equipment fabrication, and maintenance work where a low-profile head is required.

This flat socket cap screw is used across a wide range of industrial, commercial, and mechanical applications. It is well suited for metal-to-metal assemblies, machinery frames, enclosures, and fixtures where the fastener head must sit flush with or below the mating surface. The metric thread standard makes it compatible with metric-spec equipment common in HVAC systems, mechanical rooms, pump assemblies, and electrical enclosures. Installation is performed with a standard 5 millimeter hex key or Allen driver. The partial threading is appropriate for through-bolt applications where the shank spans a clearance hole before engaging a tapped bore.

Key Features

• 90-degree flat head profile allows flush or countersunk installation in prepared holes
• Hex socket drive accepts a 5 millimeter Allen key for torque application in tight spaces
• 18-8 austenitic grade A2 stainless steel construction provides corrosion resistance in wet or humid environments
• Partially threaded shank suits through-bolt installations with clearance-hole upper members
• Conforms to DIN 7991 fastener standard for dimensional consistency and interchangeability
• M8x1.25 metric thread is widely used across commercial and industrial equipment platforms

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M8x1.25 tapped holes in metal assemblies across industrial, HVAC, mechanical, and electrical equipment applications.

Installation Notes

Install and service using a 5 millimeter hex key or Allen-drive bit rated for the required torque. Ensure the receiving hole is properly countersunk at 90 degrees to achieve full head seating. Clean the threaded bore before installation to remove debris that could affect thread engagement or torque readings. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound to the threads before assembly to prevent thread damage.
