Holo-krome 770305030 Hex Socket Cap Screw M3 X0.50

Product Description

The HOLO-KROME 770305030 is a metric hex socket cap screw designed for precision fastening applications requiring corrosion resistance and high material integrity. Sized at M3 x 0.50 thread pitch with a 30 mm length under head, this fastener is partially threaded and driven by a hex socket tool. It is manufactured from Austenitic Grade A4 stainless steel with a bright, uncoated finish, meeting ISO 3506-1 and ISO 4762 standards. This screw is suited for assembly work in mechanical, HVAC equipment, electrical enclosures, and light industrial applications where stainless fasteners are specified.

This fastener fits applications calling for a small-diameter, fine-pitch metric cap screw with a hex socket drive. Its A4 stainless steel construction makes it appropriate for use in humid, wet, or corrosive environments such as pool equipment enclosures, outdoor electrical panels, and fluid-handling assemblies. Partial threading allows for controlled clamping in applications where a thread-free shank in the grip zone is required. Minimum order quantity is 10 pieces.

Key Features

• M3 x 0.50 thread pitch with 30 mm length under head for precise metric fitment
• Partially threaded shank for controlled clamping and shank-load applications
• Austenitic Grade A4 stainless steel construction for corrosion resistance
• Bright, uncoated finish — no coating thickness to account for in tight-tolerance holes
• Meets ISO 3506-1 and ISO 4762 fastener standards
• Hex socket drive for high torque input in confined spaces

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw suitable for any application specifying an M3 x 0.50 partially threaded cap screw in stainless steel.

Installation Notes

Installation is performed with the appropriate metric hex key or hex socket bit sized for M3 cap screws. Ensure mating threads are clean and free of debris before installation. Do not exceed the fastener's rated torque for M3 stainless hardware, as A4 stainless can gall if over-torqued without lubrication. Follow applicable mechanical assembly codes and equipment manufacturer guidelines when installing in pressurized or safety-critical assemblies.
