Value Collection 532140PR M8x1.25 Hex Socket Cap Screw 100mm

Product Description

The VALUE COLLECTION 532140PR is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Sized at M8x1.25 with a 100 mm length under head, this screw is partially threaded and machined from alloy steel to a 12.9 material grade, which represents the highest standard strength classification for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. The internal hex drive accepts a standard hex key for installation in tight or recessed spaces where a wrench cannot reach. This fastener is manufactured to DIN 912 and ISO 898-1 standards, confirming dimensional and mechanical consistency across the lot.

This screw is well suited for machine tool fixtures, hydraulic component mounting, jig and die work, and general fabrication where a high-clamp-load cap screw is required. The partial threading is appropriate for applications that need a smooth shank section, such as clearance-hole joints or pivot assemblies. Machinists, millwrights, and industrial maintenance technicians are the primary installers. This item is sold in a minimum order quantity of 10 pieces per order.

Key Features

• M8x1.25 thread size with 100 mm length under head for deep-reach fastening
• Alloy steel construction with 12.9 material grade for maximum tensile and proof load strength
• Partially threaded shank suits clearance-hole and pivot-joint applications
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• Internal hex drive allows installation in recessed or confined locations
• Manufactured to DIN 912 and ISO 898-1 standards for consistent dimensional and mechanical properties

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw compatible with M8x1.25 tapped holes in any assembly requiring a 12.9 grade fastener.

Installation Notes

Install using a correctly sized hex key or hex bit driver rated for high-torque applications. Grade 12.9 fasteners are susceptible to hydrogen embrittlement if improperly handled or re-plated in the field, so do not modify the finish after installation. Always verify the tapped hole thread class before driving to avoid cross-threading. Refer to applicable torque tables for 12.9 M8 fasteners when a calibrated torque wrench is required by the assembly specification.
