Value Collection 644035PR M10x1.25x45mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644035PR is a metric hex head cap screw designed for fastening applications requiring precise thread engagement and reliable clamping force. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this screw measures M10 x 1.25 thread pitch with a 45 mm length under the head. The partial threading design concentrates thread engagement in the correct grip zone, making it well suited for through-bolted and flange-mounted assemblies. A 17 mm hex drive head allows installation with standard hex wrenches and impact tools. Conformance to DIN 960 and ISO 8765 ensures dimensional consistency across production runs.

This fastener is used in mechanical, structural, and equipment assembly applications where fine-pitch metric threading is specified. Fine-pitch M10 x 1.25 screws are common in automotive components, HVAC equipment frames, pump housings, and light industrial machinery where vibration resistance or precision fit is a design requirement. The partially threaded shank provides a smooth bearing surface through clearance holes, which is typical in bolted joint assemblies requiring accurate alignment.

Key Features

• Grade 8.8 steel construction provides a balance of tensile strength and ductility for general structural fastening
• Fine-pitch M10 x 1.25 thread improves vibration resistance compared to standard M10 x 1.5 coarse thread
• Partially threaded shank suits through-bolted assemblies with clearance holes
• Bright uncoated finish — suitable for use as-is or for post-installation coating and plating
• Conforms to DIN 960 and ISO 8765 dimensional standards for interchangeability
• 17 mm hex head accommodates standard and impact wrenches

Compatibility

Designed as a standard metric hex head cap screw per DIN 960 and ISO 8765, compatible with M10 x 1.25 fine-pitch threaded assemblies in mechanical, structural, and equipment applications.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician familiar with metric fastener specifications. Always verify thread pitch compatibility before installation — M10 x 1.25 fine-pitch threads are not interchangeable with M10 x 1.5 coarse-pitch hardware. Use a calibrated torque wrench and follow the torque specifications published by the equipment or joint designer for Grade 8.8 fasteners at this diameter. Inspect threads and mating surfaces for contamination or damage before assembly.
