Value Collection 535060PR M5x0.8 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535060PR is an M5x0.8 button socket cap screw manufactured from alloy steel with a black oxide finish. It features a low-profile domed button head driven by a 3 mm hex socket and is fully threaded along its 30 mm length under head. Rated to material grade 12.9 with a hardness of 38-43 HRC, this fastener is built for high-strength clamping applications where a flush or recoressed head profile is required. The black oxide coating provides moderate corrosion resistance and reduces light reflection in finished assemblies. Installers in mechanical, industrial, and equipment fabrication trades reach for this fastener when tensile strength and a clean head profile both matter.

This screw is suited for use in mechanical assemblies, equipment panels, jigs, fixtures, and structural components where metric fasteners are specified. The M5x0.8 thread pitch and 30 mm grip length make it a common choice in light machinery, enclosures, and mounting brackets. It conforms to ANSI/ASME B18.3.4M and ISO 7380 standards, making it appropriate for applications requiring documented fastener specifications. Thread fit classes 4G and 6G are supported, giving assemblers flexibility across standard metric hole tolerances.

Key Features

• Material grade 12.9 alloy steel delivers high tensile and proof load strength
• Hardness rated 38-43 HRC for resistance to deformation under load
• Button head profile keeps the fastener low-profile in finished assemblies
• 3 mm hex socket drive for standard Allen key or hex bit installation
• Black oxide finish reduces surface reflection and provides light corrosion resistance
• Fully threaded 30 mm shank; right-hand thread direction
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as an ISO 7380-compliant metric button socket cap screw suitable for M5x0.8 threaded holes with thread fit class 4G or 6G tolerances in mechanical and industrial assemblies.

Installation Notes

Installation is performed with a 3 mm hex key or hex socket bit driver. Verify mating thread condition and hole depth before installation to ensure full thread engagement. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed rated torque values specified in ANSI/ASME B18.3.4M or the equipment manufacturer's guidelines for grade 12.9 M5 fasteners.
