Value Collection 644233PS M20 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 644233PS is a metric hex head cap screw designed for general mechanical assembly and structural fastening applications. It features an M20 x 2.50 thread profile with a 65 mm length under the head and is partially threaded along the shank. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 931 and ISO 4014 dimensional standards. The 30 mm hex drive size is compatible with standard metric wrenching tools. Licensed trades and industrial maintenance professionals use this screw in equipment assembly, frame construction, and machinery mounting where a reliable high-strength metric fastener is required.

This cap screw is suited for use in metric-standard mechanical assemblies across light industrial, commercial maintenance, and trade service environments. The partial threading and uncoated finish make it appropriate for applications where a smooth shank bearing surface is needed and where environmental coating is not a requirement. It is sold individually, making it practical for service replacement or low-volume repair work.

Key Features

• M20 x 2.50 metric thread size, partially threaded shank per DIN 931 and ISO 4014
• Grade 8.8 steel construction for reliable tensile strength in standard mechanical applications
• Bright, uncoated finish suitable for indoor or protected-environment use
• 65 mm length under the head for compatibility with medium-thickness joint assemblies
• 30 mm hex drive size works with standard metric box, open-end, and socket wrenches

Compatibility

Designed as a DIN 931 and ISO 4014 compliant metric hex head cap screw for use in M20 x 2.50 tapped holes in standard mechanical and structural assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener torque requirements for Grade 8.8 hardware. Always verify thread engagement depth and joint material compatibility before final tightening. Use a calibrated torque wrench and consult the applicable equipment service manual for torque specifications, as no torque values are published with this fastener alone. Remove any debris or corrosion from the receiving threads before installation to prevent galling.
