Value Collection 815017PR Hex Head Cap Screw M4 X 0.70

Product Description

The VALUE COLLECTION 815017PR is a metric hex head cap screw engineered for general industrial and mechanical assembly applications. It features an M4 x 0.70 thread profile with a 40 mm length under head and is manufactured from Grade 8.8 steel with a zinc-plated finish for basic corrosion resistance. The screw is partially threaded per DIN 931 and ISO 4014 standards and requires a 7 mm hex wrench or socket for installation. This fastener is suited for machinists, maintenance technicians, and assembly professionals working in metric environments.

This screw is appropriate for light-to-medium duty bolted joint assemblies in industrial machinery, equipment frames, and mechanical fixtures. The M4 thread size and 40 mm shank length make it a common choice for securing small structural members or components where a partially threaded bolt is required to pull mating surfaces together. It is sold individually with a minimum order quantity of 100 pieces.

Key Features

• M4 x 0.70 metric thread compliant with DIN 931 and ISO 4014 standards
• Grade 8.8 steel construction provides reliable tensile and yield strength for general-purpose bolted joints
• Partially threaded shank allows clamping force to develop across unthreaded grip length
• Zinc-plated finish offers basic corrosion protection in dry to mildly humid environments
• 7 mm hex drive compatible with standard metric hex sockets and wrenches
• 40 mm length under head accommodates medium-depth through-bolt applications

Compatibility

Designed as an OEM-style metric fastener for use in standard M4 x 0.70 threaded holes per DIN 931 and ISO 4014 specifications.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a 7 mm hex socket or open-end wrench. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or thread-locking compound based on the joint design requirements. Do not exceed the torque capacity appropriate for Grade 8.8 M4 fasteners as specified by the equipment manufacturer or applicable engineering standards.
