RELIABILITY: Specifically designed with a 14mm Across Flats (AF) head size, these bolts are perfect for tight-clearance areas where standard 17mm M10 bolt heads will not fit.

Key Features

• ✔ Grade 8.8 HT: High-tensile carbon steel construction.
• ✔ Small Head (AF14): 14mm head size for specialized clearance.
• ✔ Part Threaded (PT): Enhanced structural integrity in shear.
• ✔ Universal Utility: Common in ATV, Quad, and Japanese machinery.

Why is the head size 14mm for an M10 bolt?

Standard M10 bolts often use 16mm or 17mm heads. The 14mm AF head is a specialized "Small Head" design (often found in JIS standards) used in automotive and machinery environments where space is limited, allowing for easier access with smaller sockets.

How do I know if it is compatible?

Please check your existing bolt's diameter (10mm) and length (100mm). If you require a high-strength 8.8 grade bolt with a 14mm head, this is the correct part. Refer to SKU 310.0550 for exact matching.

What does "Plain" finish mean?

Plain finish, also known as "Self-Colour," means the bolt does not have an additional zinc or chrome plating. It is the natural dark steel finish resulting from the heat-treatment process.
