Description
Overview:
Mason Mate Socket Set (Grub) Screws are headless steel fasteners with a hex socket drive for precise, flush fastening in machinery and equipment. This pack includes 10 screws sized M5 x 6 (5 mm thread diameter x 6 mm length), finished in chemical black (black oxide) for added surface protection and a discreet look. The headless form allows the screw to sit fully within the component, reducing snag points and keeping moving parts clear. Commonly used to lock components on shafts or within housings, these screws suit a wide range of plant, workshop, and garden machines, from compactors and cement mixers to mowers and bench tools. Designed for dependable grip in confined spaces, they install with a standard hex key for straightforward fitting and removal.
Key Features:
- M5 x 6 size for compact, precise fastening in tight assemblies
- Headless design sits flush for a smooth, snag-free finish
- Hex socket drive for positive engagement with a hex key
- Steel construction with chemical black (black oxide) finish for wear resistance
- Corrosion-resistant surface treatment for longer service life
- Pack of 10 for maintenance, spares, and multiple fixings
- Ideal for securing collars, pulleys, gears, knobs, and couplings to shafts
- Reliable holding power when correctly tightened onto flats, keyways, or dimples
- Suitable for workshop, site, and garden machinery repairs
- Consistent sizing for easy replacement of worn or missing fasteners
Typical Applications:
Locking gears or pulleys to motor shafts, fixing shaft collars and couplings, retaining handles or knobs on equipment spindles, and securing inserts or components within housings. Widely used in construction tools, garden machinery, machine tools, and general maintenance where a low-profile, internal-drive fastener is required.
