Value Collection 643193PR Hex Head Cap Screw M10x1.25

Product Description

The VALUE COLLECTION 643193PR is a metric hex head cap screw designed for bolted assemblies requiring fine-thread engagement and consistent clamping force. Sized M10 x 1.25 x 30 mm, the screw features a 17 mm hex drive and is fully threaded from the tip to the underside of the head. It is manufactured from Grade 8.8 steel, a medium-high-strength carbon steel grade that delivers reliable tensile performance in structural and mechanical fastening applications. The bright, uncoated finish is standard for indoor or controlled-environment use where corrosion exposure is minimal. Compliance with DIN 961 and ISO 8676 standards ensures dimensional interchangeability with other conforming metric fine-pitch fasteners.

This screw is suited for precision mechanical assemblies, machine frames, automotive components, and industrial equipment where a fine M10 pitch is specified over coarse thread. The 30 mm length under head accommodates moderate material stack-ups in ferrous and non-ferrous assemblies. Maintenance technicians, machinists, and mechanical contractors working to metric specifications will encounter this fastener in both OEM builds and field repair scenarios. It is sold in a minimum order quantity of 10 pieces, making it practical for both single-repair pulls and small-batch production needs.

Key Features

• M10 x 1.25 fine-pitch thread for reduced thread engagement depth and improved resistance to vibration loosening
• Fully threaded shank allows maximum thread engagement across the entire 30 mm length under head
• Grade 8.8 steel construction provides medium-high tensile and yield strength for structural bolting
• 17 mm hex head accommodates standard metric wrenches and sockets
• Meets DIN 961 and ISO 8676 dimensional standards for drop-in interchangeability
• Bright, uncoated finish maintains true dimensional tolerances without coating buildup on threads

Compatibility

Designed as a DIN 961 and ISO 8676 conforming metric fine-pitch hex head cap screw suitable for any M10 x 1.25 tapped hole or flanged nut application requiring Grade 8.8 steel fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following the torque specifications defined in the applicable equipment service manual for M10 x 1.25 Grade 8.8 fasteners. Always ensure the mating tapped hole or nut is also rated for fine-pitch M10 x 1.25 thread before installation, as mixing coarse and fine pitch threads will damage both the fastener and the receiving material. De-energize and lock out any machinery before fastener service in accordance with applicable OSHA lockout-tagout procedures. Inspect threads for damage or contamination before installation and use a calibrated torque wrench to achieve proper clamp load.
