Value Collection 643544PR Hex Head Cap Screw M4 X 0.70 X 20 Mm

Product Description

The VALUE COLLECTION 643544PR is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It carries an M4 x 0.70 thread profile with a 20 mm length under head and is fully threaded from tip to bearing face. Manufactured from Grade 8.8 steel with a bright uncoated finish, it delivers reliable tensile strength for medium-duty bolted connections. The 7 mm hex drive accommodates standard metric wrenches and sockets. Licensed contractors, millwrights, and maintenance technicians install these fasteners during equipment assembly, fixture fabrication, and structural subassembly work.

This fastener is suited for metric-fastened assemblies in residential, commercial, and light industrial settings. Its fully threaded shank allows maximum thread engagement across the full clamping length, making it practical in thin-material and through-bolt applications. The DIN 933 and ISO 4017 standards ensure dimensional conformance, so this screw is interchangeable with other compliant metric hardware in the same size class. It is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for production runs, MRO stocking, and service van inventory replenishment.

Key Features

• M4 x 0.70 thread size with 20 mm length under head for compact bolted joints
• Fully threaded shank provides maximum thread engagement throughout the clamping zone
• Grade 8.8 steel construction offers strong tensile and proof load ratings for medium-duty use
• Bright uncoated finish suitable for dry or controlled-environment installations
• 7 mm hex drive compatible with standard metric wrenches and socket sets
• Conforms to DIN 933 and ISO 4017 dimensional standards for interchangeability

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017, dimensionally interchangeable with any M4 x 0.70 x 20 mm fully threaded hex cap screw meeting the same standards.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard 7 mm metric wrench or socket. Ensure mating threads are clean and free of debris before assembly. Do not exceed the rated clamp load for Grade 8.8 fasteners as defined by the applicable engineering specification or equipment service manual. Fasteners installed in safety-critical or structural applications should be verified against relevant standards such as ISO 898-1.
