Value Collection MP4521 Hex Head Cap Screw M10x1.25x25mm 25pk

Product Description

The Value Collection MP4521 is a metric hex head cap screw designed for general mechanical fastening applications in industrial, automotive, and equipment assembly work. This fully threaded fastener features an M10 x 1.25 mm thread specification and a 25 mm length under head, manufactured from Grade 8.8 steel with a zinc-plated finish for corrosion resistance. The 17 mm hex drive accommodates standard metric wrenches and sockets. Sold in a package of 25, this screw conforms to JIS B1180-7 standards, making it suitable for applications where metric fastener specifications and dimensional accuracy are required. Machinists, millwrights, and mechanical assemblers are the typical installers.

This fastener is appropriate for use in metric-dimensioned assemblies across residential equipment, light industrial machinery, and automotive components. The fine 1.25 mm thread pitch provides stronger thread engagement in softer materials or tapped holes where coarse threads are not specified. The zinc plating offers a baseline level of protection against oxidation in indoor and light outdoor environments. Each package contains 25 screws, suitable for small-volume jobs or as a replenishment supply for fastener inventory.

Key Features

• M10 x 1.25 mm fine metric thread, fully threaded along the 25 mm shank length
• Grade 8.8 steel construction for reliable tensile and yield strength in mechanical assemblies
• Zinc-plated finish provides baseline corrosion resistance for indoor and light-duty environments
• 17 mm hex head fits standard metric sockets and open-end wrenches
• Conforms to JIS B1180-7 metric fastener standard
• Package quantity of 25 per unit for efficient stocking and small-batch use

Compatibility

Designed for use in metric-threaded assemblies requiring an M10 x 1.25 fine-pitch fastener per JIS B1180-7 specification. Verify thread pitch and hole depth before installation to confirm fit.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or assemblers using a 17 mm metric socket or wrench. Confirm that the mating threaded hole or nut matches the M10 x 1.25 fine pitch before driving the fastener. Do not mix fine-pitch and coarse-pitch M10 hardware in the same assembly. Apply thread lubricant or threadlocker only as specified by the equipment manufacturer or applicable engineering standard.
