Value Collection 815A02PS M4 Hex Head Cap Screw 18mm

Product Description

The VALUE COLLECTION 815A02PS is a fully threaded metric hex head cap screw designed for general mechanical fastening applications. Built to Grade 8.8 steel with a zinc-plated finish, it delivers reliable tensile strength and corrosion resistance in a compact M4 x 0.70 thread profile. The 18 mm length under head and 7 mm hex drive make it compatible with standard metric tooling. This fastener meets DIN 933 and ISO 4017 standards, making it suitable for use in assemblies where dimensional and mechanical compliance is required. Electricians, HVAC technicians, plumbers, and general mechanical contractors frequently use Grade 8.8 metric screws when assembling equipment enclosures, mounting brackets, and panel hardware.

This screw is suited for light-to-medium duty fastening in metric-dimensioned assemblies. Typical applications include securing electrical enclosures, control panel components, HVAC equipment mounting hardware, and mechanical sub-assemblies where an M4 thread pitch of 0.70 mm and an 18 mm grip length are specified. The zinc plating provides baseline protection against moisture and mild corrosion in indoor and sheltered outdoor environments. This item is sold individually but requires a minimum order quantity of 100 units per order.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength for general mechanical fastening
• Zinc-plated finish offers corrosion resistance in indoor and sheltered applications
• Fully threaded shank along the full 18 mm length under head for maximum thread engagement
• 7 mm hex drive compatible with standard metric wrenches and sockets
• Meets DIN 933 and ISO 4017 dimensional and mechanical standards
• M4 x 0.70 metric thread profile for use in metric-spec assemblies

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant M4 x 0.70 fully threaded hex head cap screw, compatible with any metric-threaded M4 x 0.70 tapped hole or nut in equipment assemblies requiring Grade 8.8 fasteners.

Installation Notes

Install using a 7 mm metric wrench or socket driver. Ensure the mating thread is clean and free of debris before driving. Do not exceed the torque rating specified for Grade 8.8 M4 fasteners per the relevant equipment manufacturer guidelines. Zinc plating is not rated for immersion or high-humidity environments where stainless or hot-dip galvanized fasteners would be more appropriate.
