Holo-krome 770508008 M5 X 0.80 Hex Socket Cap Screw

Product Description

The HOLO-KROME 770508008 is a metric hex socket cap screw with an M5 x 0.80 thread and an 8 mm length under the head. It is fully threaded along its shank and driven with a hex key. Constructed from austenitic Grade A4 stainless steel with a bright, uncoated finish, this fastener meets ISO 4762 and ISO 3506-1 standards. It is used by mechanical contractors, industrial maintenance technicians, HVAC fabricators, and equipment assemblers wherever a clean, corrosion-resistant metric fastener is required in a compact form factor.

This screw is well suited for light-duty mechanical assemblies, equipment panels, HVAC component mounting brackets, and indoor or outdoor installations where moisture or chemical exposure demands stainless steel hardware. The compact M5 size fits tight clearance applications where standard hex-head fasteners cannot be used. Minimum order quantity is 10 pieces per order.

Key Features

• M5 x 0.80 metric thread, fully threaded shank for maximum thread engagement
• 8 mm length under head suits shallow through-hole and blind-hole applications
• Austenitic Grade A4 stainless steel provides strong corrosion resistance
• Bright, uncoated finish maintains dimensional accuracy without coating buildup
• Hex socket drive allows installation in recessed or close-clearance locations
• Meets ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw suitable for any application requiring an M5 x 0.80 fully threaded stainless steel fastener conforming to ISO 3506-1 Grade A4.

Installation Notes

Installation requires an appropriately sized metric hex key or Allen driver. Verify mating thread condition and hole depth before fastening to avoid cross-threading or bottoming out in blind holes. Stainless steel fasteners are susceptible to galling during installation — apply a small amount of compatible anti-seize compound when torquing into stainless or aluminum mating threads. Always follow equipment manufacturer torque guidelines and applicable mechanical codes for the specific assembly.
