Value Collection 643550PR M4 Hex Head Cap Screw 45mm

Product Description

The VALUE COLLECTION 643550PR is a metric hex head cap screw engineered for general-purpose mechanical assembly where dimensional precision and material strength are required. Built to Grade 8.8 steel with a bright uncoated finish, this fastener delivers dependable tensile strength in a compact M4 x 0.70 thread profile. The fully threaded shank spans 45 mm under the head, making it suitable for through-bolted connections and threaded-insert applications. A 7 mm hex drive allows installation with standard metric hex wrenches or sockets. It conforms to DIN 933 and ISO 4017 standards, ensuring interchangeability with other metric hardware meeting those specifications. Mechanics, millwrights, and maintenance technicians will find this screw appropriate for light-to-medium duty fastening tasks.

This screw is used in a wide range of residential and commercial applications including machinery assembly, equipment mounting, fixture fabrication, and general maintenance work. The M4 x 0.70 thread size is common in small mechanical assemblies, electronic enclosures, HVAC component brackets, and light structural connections. Its DIN 933 and ISO 4017 compliance means it integrates cleanly into metric fastener systems without modification or special tooling.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in general mechanical applications
• Fully threaded shank along the full 45 mm under-head length for maximum thread engagement
• M4 x 0.70 metric thread form conforms to DIN 933 and ISO 4017 standards
• 7 mm hex drive compatible with standard metric sockets and wrenches
• Bright uncoated finish suitable for indoor or protected installations where corrosion resistance is not a primary requirement

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant metric fastener, compatible with M4 x 0.70 threaded holes and inserts in any application requiring Grade 8.8 hex head cap screws.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard 7 mm metric socket or open-end wrench. De-energize or lock out any equipment before installing fasteners in live machinery per applicable OSHA lockout/tagout procedures. Do not use uncoated steel fasteners in direct outdoor or high-humidity environments without additional corrosion protection such as plating or sealant. Minimum order quantity is 100 pieces; plan fastener stock accordingly for project requirements.
