Holo-krome 770508050 Hex Socket Cap Screw M5 X 0.80

Product Description

The HOLO-KROME 770508050 is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, industrial equipment, and structural applications. It features an M5 x 0.80 thread size with a 50 mm length under the head and is partially threaded. Manufactured from Austenitic Grade A4 stainless steel with a bright, uncoated finish, it delivers strong corrosion resistance in wet, chemical, or marine environments. The internal hex drive accepts a standard hex key, allowing high torque application in tight clearance situations. This fastener conforms to ISO 3506-1 and ISO 4762 standards. Licensed mechanics, maintenance technicians, and trade professionals working in corrosive or sanitary environments specify this grade for reliable, long-term joint integrity.

This screw is suited for residential and commercial mechanical systems, fabricated equipment, pump assemblies, enclosures, and instrumentation panels where metric fasteners are required. The A4 stainless grade is commonly selected for outdoor installations, food-processing environments, marine hardware, and any application where Grade 18-8 corrosion resistance falls short. The partial threading is standard for clamping applications where the unthreaded shank bears shear load across a joint interface.

Key Features

• M5 x 0.80 thread with 50 mm length under head for precise metric fastening
• Austenitic Grade A4 stainless steel construction for superior corrosion resistance
• Partially threaded shank handles shear loads at joint interfaces
• Bright uncoated finish maintains dimensional accuracy and thread fit
• Internal hex drive allows high-torque application in confined spaces
• Conforms to ISO 3506-1 and ISO 4762 fastener standards

Compatibility

Designed as a metric ISO 4762 hex socket cap screw compatible with standard M5 x 0.80 threaded inserts, nuts, and tapped holes per ISO metric fastener specifications.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or licensed tradespeople using a calibrated hex key or socket driver matched to the M5 fastener drive size. Always de-energize and lock out equipment before fastener service on powered systems. Torque to the joint specification for the host assembly and material per applicable standards. Do not use impact drivers on stainless fasteners, as galling of the threads may result in fastener seizure.
