Description
Overview:
The Hex Socket Head Cap Screw M16 x 25 is a high‐tensile fastener for heavy‐duty assemblies in plant, machinery, and workshop fixtures. Manufactured from Grade 12.9 alloy steel (typical minimum tensile strength 1220 MPa), it provides high clamping force where reliability and limited head clearance are important. The chemical black (black oxide) finish offers a clean look with light corrosion resistance. Size: M16 diameter x 25 mm length (approx 16 mm ≈ 5/8 in diameter, 25 mm ≈ 1 in length). The internal hex drive allows positive engagement and quick installation using a 14 mm hex key (Allen key). Sold individually ("each") for precise quantities, it's suitable for maintenance, repair, and OEM builds across construction equipment, agricultural machinery, garden machinery, and general industrial equipment.
Key Features:
- Grade 12.9 high‐tensile alloy steel for maximum strength in critical joints
- Chemical black (black oxide) finish for low glare and light corrosion resistance
- M16 x 25 mm size for robust, compact clamping (approx 5/8 in x 1 in)
- Hex socket head for easy access in tight spaces and reduced risk of tool slip
- Accepts a 14 mm hex key for consistent torque application
- Precision‐machined threads for smooth assembly and secure seating
- Ideal for tapped holes; compatible with high‐tensile washers where required
- Sold individually to match exact repair or build quantities
- Common across industrial, automotive, and machinery fixtures
- Zinc‐plated and stainless variants may be available where extra corrosion resistance is needed
Typical Applications:
Securing brackets, guards, pulleys, flanges, and housings on construction plant, compressors, pumps, gearboxes, and garden machinery. Suitable for repairs, upgrades, and jigs where a strong internal‐hex fastener is preferred. Use where high preload, accurate alignment, and a compact head profile are required. Always tighten to the specification for your assembly.
