Description
Overview:
These M6 x 60 hex socket head cap screws are high‐tensile fasteners for reliable assembly in construction and garden machinery, plant equipment, tools, and jigs. Made from alloy steel to strength class 12.9, they deliver high clamping force and long service life under load. The chemical black (black oxide) finish provides a neat appearance and helps resist corrosion when used indoors or with light protection. The hex socket head allows positive engagement with a hex key or bit in tight spaces and recessed holes. Each screw measures 6 mm diameter by 60 mm length (approx. 2.36 in). Supplied in a pack of 10 for convenient maintenance and replacements across multiple fixings. Manufacturer Part Number: 903 0291 200PK.
Key Features:
- Grade 12.9 alloy steel for very high tensile strength and dependable clamping
- M6 x 60 mm size suits common fabrication and machinery mounting points (approx. 2.36 in length)
- Chemical black finish for enhanced corrosion resistance and low glare
- Hex socket head for secure drive and easy access in confined assemblies
- Accurate metric threads for consistent fit with tapped holes and matching nuts
- Cap head design sits neatly in counterbored holes and fixtures
