Value Collection 42004 M4 X 0.70 X 20 Mm Hex Cap Screw 50-pack

Product Description

The VALUE COLLECTION 42004 is a fully threaded metric hex head cap screw engineered for general-purpose mechanical assembly and fastening applications. Built to Grade 8.8 steel with a zinc-plated finish, this screw delivers reliable tensile strength and corrosion resistance in a compact M4 x 0.70 profile. The 20 mm length under head and 7 mm hex drive make it suitable for use with standard metric hex wrenches and socket sets. It conforms to DIN 933 and ISO 4017 standards, ensuring dimensional consistency across production and repair work. Sold in a package of 50, this fastener is appropriate for machinists, maintenance technicians, and assembly professionals working in metric environments.

This screw is used in light-duty to medium-duty mechanical assemblies where a fully threaded metric fastener is required. Common applications include equipment panels, brackets, housings, and fixture mounting in industrial, HVAC, and general maintenance settings. The zinc-plated finish provides basic protection against oxidation in dry to mildly humid indoor environments. Its fully threaded shank is suited for clamping thin materials or threading into tapped holes without the need for a separate nut when clearance allows.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in metric fastening applications
• Zinc-plated finish provides corrosion resistance in dry and lightly humid conditions
• Fully threaded shank allows engagement along the entire length for thin-material clamping
• Conforms to DIN 933 and ISO 4017 dimensional standards for consistent fitment
• 7 mm hex drive compatible with standard metric wrenches and socket sets
• Packaged in quantities of 50 for bench stock and production use

Compatibility

Designed as a standard metric replacement or stock fastener for any application requiring an M4 x 0.70 fully threaded hex head cap screw meeting DIN 933 or ISO 4017 specifications.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener standards. Always verify the mating thread specification and tapped hole depth before installation to avoid cross-threading or bottoming out. Use a calibrated torque wrench appropriate for M4 Grade 8.8 fasteners and follow the equipment manufacturer's torque specifications. Do not mix metric and imperial fasteners in the same assembly.
