Value Collection -42793-1 Hex Socket Cap Screw M12x1.75

Product Description

The VALUE COLLECTION -42793-1 is a partially threaded hex socket cap screw designed for high-strength mechanical fastening applications. The screw features an M12 x 1.75 metric thread and a 120 mm length under head. It is manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and reduces light reflection on the fastener surface. The drive type is internal hex, also known as Allen or socket head, allowing high torque application with a hex key or socket driver. The material grade is 12.9, indicating a high-tensile fastener suitable for demanding structural and mechanical assemblies.

This cap screw is used in mechanical, industrial, and structural assembly work where a recessed drive and a strong clamping force are required. The partially threaded shank provides a smooth bearing surface in the grip area, making it well suited for applications where shear loads are a concern or precise shaft alignment is needed. It conforms to DIN 912 and ISO 898-1 fastener standards, making it a common choice in machine building, equipment fabrication, and general maintenance applications across manufacturing and industrial trades.

Key Features

• M12 x 1.75 metric thread for standard metric fastening applications
• 120 mm length under head with partial threading for shear-load and alignment-sensitive joints
• Alloy steel construction with 12.9 material grade for high-tensile strength
• Black oxide coating provides mild corrosion resistance and low-reflectance surface
• Internal hex drive allows high-torque installation with standard hex keys or socket tools
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric socket cap screw compatible with M12 x 1.75 threaded bores in machinery, equipment frames, and structural assemblies requiring a 12.9 grade fastener.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a properly sized hex key or socket driver rated for high-torque applications. Always verify thread engagement depth and bore condition before installation. Do not mix metric and unified thread standards in the same assembly. Follow applicable machinery safety lockout and tagout procedures before servicing any fastened assembly.
