Holo-krome 770305035 Hex Socket Cap Screw M3 X 0.50

Product Description

The HOLO-KROME 770305035 is a metric hex socket cap screw sized M3 x 0.50 with a 35 mm length under the head. It is manufactured from Austenitic Grade A4 stainless steel with a bright, uncoated finish. The partially threaded shank provides a clamping zone free of thread engagement, which is useful when a specific grip length is required. This fastener conforms to ISO 4762 and ISO 3506-1 standards. Maintenance technicians, millwrights, and mechanical contractors install this type of fastener in assemblies that require corrosion resistance and precise socket-drive torque application.

This screw is suited for light-duty mechanical assemblies, enclosures, brackets, and equipment panels where stainless steel corrosion resistance is required. The hex socket drive accepts a standard metric Allen key or hex bit driver, making it practical in tight clearance situations. The M3 x 0.50 thread pitch is common in instrumentation, HVAC controls, electrical enclosures, and small mechanical sub-assemblies across residential and light commercial applications.

Key Features

• M3 x 0.50 metric thread with 35 mm length under head
• Partially threaded shank for controlled grip and clamping
• Austenitic Grade A4 stainless steel for corrosion resistance
• Bright, uncoated finish — no plating interference with thread fit
• Hex socket drive for use in tight clearance installation points
• Conforms to ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as an OEM-style metric hex socket cap screw for general mechanical assemblies requiring an M3 x 0.50 thread and 35 mm under-head length in stainless steel.

Installation Notes

Installation requires a metric hex key or hex bit driver sized for an M3 socket cap screw. De-energize or lock out equipment before servicing any fastened assembly. Avoid mixing stainless steel fasteners with dissimilar metals in corrosive environments to prevent galvanic corrosion. Follow applicable equipment manufacturer torque guidance and relevant mechanical codes for the specific assembly being serviced.
