Holo-krome 560002654 Socket Head Cap Screw Set 285pc

Product Description

The HOLO-KROME 560002654 is a 285-piece socket head cap screw assortment made from alloy steel to Class 12.9 specifications. Class 12.9 is the highest standard metric strength grade, delivering high tensile and proof load values suited for demanding fastening applications. The kit spans M6 through M10 thread sizes across 24 distinct size variations, with lengths starting at 12 millimeters. It is used by machinists, millwrights, maintenance technicians, and mechanical contractors who need a broad range of metric fasteners on hand for equipment assembly, repair, and fabrication work. The assortment ships as a single package weighing 20 pounds.

This assortment is suited for industrial maintenance, machine tool service, and general mechanical assembly environments where metric socket head cap screws are frequently required. The M6 through M10 range covers the most common frame, bracket, and component mounting applications found in manufacturing equipment, hydraulic assemblies, and structural fixtures. Having 24 size variants in one kit reduces the need for multiple individual orders and keeps a working inventory of critical fastener sizes available at the job site or shop bench.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or mechanical technician familiar with metric fastener torque requirements for Class 12.9 hardware. Always verify thread engagement depth and confirm the mating material can handle the clamping loads associated with high-strength Class 12.9 fasteners before final assembly. Use a calibrated torque wrench appropriate for the fastener size. Follow applicable equipment manufacturer specifications and relevant industry standards when determining torque values.
