Value Collection 532138PR M8 X 1.25 Hex Socket Cap Screw 90mm

Product Description

The VALUE COLLECTION 532138PR is a metric hex socket cap screw designed for high-strength fastening applications in industrial and mechanical assemblies. The screw features an M8 x 1.25 thread pitch and a 90 mm (approximately 3.54 inches) length under head. It is partially threaded and constructed from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. Grade 12.9 material rating indicates an exceptionally high tensile strength, making this fastener appropriate for critical bolted joints. Licensed machinists, millwrights, and equipment technicians are the primary installers.

This fastener is suited for use in machinery, tooling fixtures, hydraulic components, and structural assemblies where a recessed hex drive and high clamping force are required. The DIN 912 and ISO 898-1 standards govern its dimensional and mechanical properties, making it interchangeable with other conforming metric socket cap screws of the same thread and length specification. It is sold in a minimum order quantity of 10 pieces per order.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• M8 x 1.25 metric thread with 90 mm length under head, partially threaded shank
• Hex socket (Allen) drive for recessed, torque-efficient installation
• Black oxide finish for reduced surface reflectivity and light corrosion protection
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Minimum order quantity of 10 pieces ensures job-site supply availability

Compatibility

Designed as a DIN 912 and ISO 898-1 conforming replacement or stock fastener for any assembly calling for an M8 x 1.25 Grade 12.9 partially threaded hex socket cap screw with a 90 mm length under head.

Installation Notes

Installation requires a properly sized metric hex key or hex bit driver. Verify the mating thread is clean and free of debris before installation. Apply thread lubricant or specified thread compound according to the joint design requirements, as dry and lubricated torque values differ significantly for Grade 12.9 fasteners. Always confirm the correct length under head and thread engagement depth for the specific application before final assembly.
