Holo-krome 77060 Hex Socket Cap Screw M4 X 0.70 Stainless

Product Description

The HOLO-KROME 77060 is an M4 x 0.70 metric hex socket cap screw designed for precision fastening applications requiring corrosion resistance and reliable clamping force. Manufactured from Austenitic Grade A4 stainless steel with a bright uncoated finish, this screw delivers strong performance in wet, chemical-exposed, or marine environments. The 20 mm length under head and fully threaded shank make it well suited for through-hole and blind-hole assemblies where maximum thread engagement is required. A hex drive socket interface allows controlled torque application with standard Allen keys or hex bit drivers. Certified to ISO 4762 and ISO 3506-1 for dimensional and mechanical compliance.

This screw is used across a broad range of light industrial, mechanical, HVAC equipment, electrical enclosure, and plumbing fixture assembly applications. The M4 thread size is common in panel mounting, small equipment frames, and instrumentation assemblies. Grade A4 stainless construction makes it appropriate for outdoor, coastal, or high-humidity installations where carbon steel fasteners would corrode. Trade mechanics, equipment fabricators, and service technicians installing or repairing equipment with metric hardware will find this fastener a direct-fit option for M4 threaded holes.

Key Features

• M4 x 0.70 metric thread for precise, standardized fitment
• 20 mm length under head with fully threaded shank for maximum thread engagement
• Austenitic Grade A4 stainless steel construction for corrosion resistance in wet and chemical environments
• Bright uncoated finish — no coating thickness to affect thread tolerance
• Hex socket (Allen) drive for controlled torque and recessed installation clearance
• Certified to ISO 4762 and ISO 3506-1 fastener standards

Compatibility

Designed as a standard ISO 4762 metric hex socket cap screw for use in any M4 x 0.70 threaded application requiring Grade A4 stainless steel fasteners.

Installation Notes

Installation is performed with a correctly sized hex key or Allen bit driver matched to the M4 socket head. Verify thread engagement depth before final torque to avoid stripping in shallow blind holes. Do not mix stainless fasteners with dissimilar metals in highly galvanic environments without appropriate isolation measures. Apply anti-seize compound if repeated removal is expected, as Grade A4 stainless screws can gall in stainless-threaded holes.
