Value Collection FHS1X0530-050BX M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0530-050BX is a metric flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. It features a 90-degree flat head driven by a 3 mm hex socket key and is manufactured from 18-8 austenitic stainless steel, Grade A2, conforming to DIN 7991. The M5x0.8 thread and 30 mm length make it a common choice in machinery, instrumentation, and light structural assemblies where corrosion resistance is required alongside a low-profile head seating flush with the mating surface. Installation requires no specialty tooling beyond a standard 3 mm hex key.

This screw is suited for residential, commercial, and industrial maintenance applications where metric fasteners are specified. The DIN 7991 standard makes it interchangeable with metric-spec assemblies across mechanical, plumbing support, HVAC bracket, and electrical enclosure applications. It is sold in a minimum order quantity of 50 pieces, making it appropriate for stocking or batch installations requiring consistent corrosion-resistant hardware throughout the assembly.

Key Features

• 90-degree flat head seats flush with countersunk surfaces, eliminating protrusion
• 3 mm hex socket drive for precise torque application in tight spaces
• 18-8 austenitic Grade A2 stainless steel provides strong corrosion resistance in wet and outdoor environments
• M5x0.8 metric thread conforms to DIN 7991 standard for broad interchangeability
• Partially threaded shank for clamping and alignment in through-bolt applications
• Sold in multiples of 50 for efficient stocking and batch installation use

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for countersunk M5 threaded applications across mechanical assemblies, support structures, and equipment enclosures requiring stainless steel hardware.

Installation Notes

Install using a 3 mm hex key or hex bit driver; ensure the mating surface is properly countersunk at 90 degrees to achieve full flush seating. De-energize any electrical equipment and depressurize or isolate any fluid systems before fastener service. Apply anti-seize compound if installing in dissimilar metal assemblies or high-moisture environments to prevent galling common to stainless steel fasteners. Follow applicable mechanical codes and equipment manufacturer torque guidance for M5 fasteners in the specific application.
