Value Collection 42798 M16x2 Hex Socket Cap Screw 80mm

Product Description

The VALUE COLLECTION 42798 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features an M16 x 2.00 mm thread profile with an 80 mm length under head and is partially threaded along the shank. Manufactured from alloy steel with a black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating very high tensile and proof-load capacity. Installation requires a standard hex key or Allen driver. This fastener is sold individually with a minimum order quantity of 10 pieces.

The 42798 is suited for use in machine tool construction, hydraulic equipment, die and mold assemblies, and other industrial or OEM applications where a recessed-drive, high-strength metric cap screw is required. The partially threaded shank provides a clamping zone that resists shear forces in close-tolerance bored holes. Licensed machinists, millwrights, maintenance mechanics, and mechanical assemblers are the primary installers of this fastener type.

Key Features

• M16 x 2.00 mm thread — standard coarse pitch per DIN 912 and ISO 898-1
• 80 mm length under head, partially threaded shank for shear-resistant clamping
• Alloy steel construction with 12.9 material grade for maximum tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Hex socket drive accepts standard Allen or hex key tooling
• Minimum order quantity of 10 pieces per order

Compatibility

Designed as a direct-fit replacement or OEM-style metric hex socket cap screw for applications specifying M16 x 2.00 mm thread, 80 mm length under head, DIN 912 geometry, and 12.9 grade alloy steel.

Installation Notes

Installation should be performed by a qualified machinist or mechanical assembler using a calibrated torque wrench and the correct hex key size for M16 socket cap screws. Clean and inspect mating threaded holes before installation to ensure thread integrity. Apply thread lubricant or threadlocker only as specified by the equipment manufacturer. Do not exceed the torque specifications listed in the relevant DIN or ISO fastener standard for Grade 12.9 fasteners.
