Value Collection A996751 M20x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION A996751 is a fully threaded hex socket cap screw sized M20 x 2.50 with a 65 mm length under head. Manufactured from alloy steel and finished with a black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards at material grade 12.9 — the highest common strength class for metric socket cap screws. The drive type is internal hex, requiring a hex key or Allen-style driver for installation. This screw is sold in a package of five and is suited for heavy-duty mechanical assemblies, machine components, and structural joints where high clamp load and corrosion resistance are required.

Grade 12.9 alloy steel socket cap screws in M20 x 2.50 are commonly used in industrial machinery, hydraulic equipment, dies, tooling fixtures, and structural steel assemblies. The black oxide finish provides mild corrosion resistance and reduces light glare on machined surfaces. This fastener is appropriate for applications where controlled torque and high tensile strength are critical. Machinists, millwrights, maintenance technicians, and mechanical contractors are the typical installers.

Key Features

• M20 x 2.50 thread size with 65 mm length under head
• Fully threaded along the shank length
• Grade 12.9 alloy steel for maximum tensile strength in metric fasteners
• Black oxide finish for mild corrosion resistance and surface protection
• Conforms to DIN 912 and ISO 898-1 standards
• Internal hex drive for high-torque installation in confined spaces

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a fully threaded M20 x 2.50 hex socket cap screw per DIN 912 specification at grade 12.9.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener torque specifications for grade 12.9 hardware. Always ensure the mating threaded bore is clean and free of debris before installation. Refer to your equipment manufacturer torque tables for M20 grade 12.9 values — do not substitute values from lower-grade fastener charts. Lubrication of threads may alter the required torque value; follow the assembly drawing or service manual for the specific application.
