The VALUE COLLECTION 644181PS is a metric hex head cap screw designed for general-purpose mechanical fastening in structural, industrial, and equipment assembly applications. The fastener is manufactured from Grade 8.8 steel with a bright, uncoated finish and features partial threading along the shank. It measures M16 x 2.00 thread size with a 110 mm length under the head and uses a 24 mm hex drive. Grade 8.8 designates medium-high tensile strength, making it a standard choice for bolted joints where controlled clamping force and predictable load performance are required. Machinists, millwrights, and maintenance technicians routinely specify this class of fastener across a wide range of mechanical systems.
This cap screw is suited for residential equipment, commercial machinery, and industrial fabrication where metric fasteners conforming to DIN 931 and ISO 4014 standards are called out. The partially threaded shank provides a smooth bearing surface between clamped components, which is beneficial in applications requiring precise shear resistance or where the bolt passes through a clearance hole before engaging a threaded bore. It fits standard metric tooling and is compatible with M16 metric nuts and threaded inserts.
Designed as a DIN 931 and ISO 4014 compliant metric fastener for use with M16 x 2.00 threaded hardware in standard metric bolted assemblies.
Installation should be performed by qualified mechanical trades personnel using calibrated torque wrenches to achieve the required clamping load for Grade 8.8 hardware per applicable engineering specifications. Ensure all mating threads are clean and free of debris before assembly. Do not mix metric and unified thread fasteners in the same joint. For safety-critical or structural applications, consult the relevant design standard or engineering authority for proper torque and preload requirements.
