Value Collection 643527PS M3x0.50x25mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643527PS is a metric hex head cap screw designed for general mechanical fastening in assemblies requiring precise thread engagement and reliable clamping force. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener delivers the tensile strength and dimensional consistency expected in industrial and trade applications. The screw features an M3 x 0.50 thread, a 25 mm length under head, and full threading along the shank, making it suitable for through-hole and standard tapped-hole installations. A 5.5 mm hex drive is used for installation with standard metric hex tooling.

This fastener is used in light mechanical assemblies, equipment fabrication, HVAC component mounting, electrical enclosures, and general trade work where metric hardware is specified. The fully threaded shank is well suited for short-grip applications and thin material stacking. Conformance to DIN 933 and ISO 4017 standards ensures dimensional interchangeability with other compliant metric fasteners. This screw is sold individually but carries a minimum order quantity of 100 units per order.

Key Features

• M3 x 0.50 metric thread with 25 mm length under head for precise fitment in tapped metric holes
• Fully threaded shank per DIN 933 and ISO 4017 standards for dimensional consistency
• Grade 8.8 steel construction provides high tensile strength appropriate for structural fastening
• Bright uncoated finish suitable for dry or lightly controlled environments
• 5.5 mm hex drive compatible with standard metric wrenches and sockets
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant metric hex head cap screw for use in any application specifying an M3 x 0.50 x 25 mm fully threaded hex fastener.

Installation Notes

Installation should be performed by a qualified technician or trades professional using a properly sized 5.5 mm metric hex wrench or socket. Ensure the mating tapped hole or nut is clean, undamaged, and matched to M3 x 0.50 thread specifications before installation. Do not exceed the rated capacity of the fastener, and do not substitute this screw in safety-critical structural applications without engineering verification. Follow applicable equipment manufacturer guidelines and relevant mechanical codes when specifying or replacing fasteners in trade equipment.
