Types of Metric Cup Point Set Screws We Offer

Metric Cup Point Hex Socket Set Screw, 45H ISO 4029/DIN 916, Thermal Black Oxide

These 45H alloy steel screws provide dependable holding power with a concave cup point that bites into the surface. The thermal black oxide finish delivers a dark appearance with mild corrosion resistance. They are often used in machinery and rotating equipment where vibration resistance is essential.

Metric Cup Point Hex Socket Set Screw, 45H ISO 4029/DIN 916, Zinc CR+3 Bake

This version features a zinc CR+3 baked finish for added corrosion protection. The baked process minimizes hydrogen embrittlement, making these screws suitable for safety-critical assemblies. Their silver finish provides both durability and a clean appearance in exposed applications.

Metric Cup Point Hex Socket Set Screw, 45H ISO 4029/DIN 916, Mechanical Zinc CR+3, Alloy

With a mechanical zinc CR+3 coating, these alloy steel screws combine strength with enhanced protection. The mechanical process avoids hydrogen embrittlement, making them ideal for high-strength fastening. They are widely used in aerospace and heavy machinery applications where both safety and durability are required.

Metric Stainless A2 Cup Point Hex Socket Set Screw, DIN 916

A2 stainless cup point set screws provide moderate strength along with reliable resistance to rust and moisture. Their concave design ensures secure holding power in machinery and equipment subject to vibration. They are commonly chosen for outdoor, marine, and food-grade applications.

Metric Stainless A4 (316) Cup Point Hex Socket Set Screw, DIN 916

316 stainless steel screws deliver superior corrosion resistance, especially in saltwater and harsh chemical environments. The cup point design ensures firm grip while preventing loosening under vibration. These screws are indispensable in marine, chemical, and offshore projects where both strength and corrosion resistance are critical.

Material Options

South Coast Fasteners stocks metric cup point set screws in alloy steel 45H for high strength and in stainless grades A2 and A4 for corrosion resistance.

Alloy Steel 45H

45H alloy steel provides strong mechanical properties for secure fastening in machinery and equipment. Its hardness allows the cup point to bite firmly into the surface, preventing slippage and loosening. It is widely used in industrial and automotive assemblies.

Stainless Steel A2

A2 stainless steel offers moderate strength along with protection against rust in outdoor and marine environments. It is often specified in food processing equipment, architectural applications, and general assemblies where moisture resistance is required.

Stainless Steel A4 (316)

A4 stainless steel provides maximum resistance to chlorides, saltwater, and harsh chemicals. It is used in offshore platforms, chemical plants, and marine installations. These screws ensure long service life even under constant exposure to aggressive elements.

Available Finishes

South Coast Fasteners offers metric cup point set screws in finishes designed to extend service life and enhance performance.

Thermal Black Oxide

Thermal black oxide creates a smooth, dark finish that reduces glare and provides mild protection against corrosion. It also helps retain oil for lubrication and wear resistance. This finish is frequently chosen for machinery and equipment where both durability and appearance matter.

Zinc CR+3 Bake

Zinc CR+3 bake delivers a bright silver coating with strong corrosion protection. The baking process minimizes hydrogen embrittlement, making it a preferred finish for high-strength screws. It is widely used in structural and mechanical assemblies.

Mechanical Zinc CR+3

Mechanical zinc CR+3 avoids hydrogen embrittlement through a non-electrolytic process. This finish provides reliable corrosion resistance while maintaining the strength of the fastener. It is ideal for aerospace and high-strength machinery applications.
