Value Collection 44419 Hex Head Cap Screw M5x0.80x40mm

Product Description

The VALUE COLLECTION 44419 is a metric hex head cap screw engineered for high-strength fastening applications. Built to Grade 10.9 steel specification, it delivers superior tensile strength compared to standard-grade fasteners, making it well suited for assemblies subject to mechanical stress or vibration. The screw features an M5 x 0.80 thread profile with a 40 mm length under the head and a zinc-plated finish that provides baseline corrosion resistance. It is partially threaded, and the 8 mm hex drive is compatible with standard metric hex wrenches and sockets. This fastener conforms to ASME B18.0.3.1M and is sold in packages of 50 units.

This screw is used across a broad range of mechanical, industrial, and trade applications wherever a metric M5 fastener with high tensile strength is required. Common installation scenarios include equipment assemblies, bracket mounting, panel attachment, and general machine maintenance. The zinc plating is appropriate for indoor and light-duty environments. It is suitable for use by HVAC technicians, electricians, plumbers, millwrights, and general maintenance professionals working on mechanical assemblies that specify metric hardware.

Key Features

• Grade 10.9 steel construction for high tensile and proof load strength
• M5 x 0.80 metric thread with 40 mm length under head
• Partially threaded shank for controlled clamping in standard fastening applications
• 8 mm hex drive compatible with standard metric sockets and wrenches
• Zinc-plated finish provides corrosion resistance in typical indoor service environments
• Conforms to ASME B18.0.3.1M dimensional standard

Compatibility

Designed as a standard metric hex head cap screw for any application specifying an M5 x 0.80 x 40 mm Grade 10.9 partially threaded fastener per ASME B18.0.3.1M.

Installation Notes

Installation should be performed by qualified mechanical or trade personnel using a calibrated metric socket or wrench sized to 8 mm. Verify thread engagement depth and mating material compatibility before fastening, particularly when installing into aluminum or plastic housings where over-torquing can cause damage. Zinc-plated fasteners are not recommended for continuously wet or corrosive environments without additional protective measures. Always follow the torque specifications provided by the equipment manufacturer for the specific assembly.
