Stainless Steel Hex Head SEMS Bolt with Hole
Product Overview
The Stainless Steel Hex Head SEMS Bolt with Hole is a pre-assembled fastener designed for ease of use, high durability, and enhanced safety in bolted connections. These bolts combine a standard hex head bolt with a built-in washer, secured to prevent separation, and a drilled hole, enabling additional fastening with wire or safety mechanisms. This integrated solution minimizes assembly time and ensures consistent, reliable installations in critical applications.
As experts in the fastener industry, Flybear Fastener offers SEMS bolts crafted with precision, using premium stainless steel materials that resist corrosion and wear across a variety of demanding environments.

Materials and Manufacturing Process
Our Stainless Steel Hex Head SEMS Bolt with Hole is typically manufactured from corrosion-resistant stainless steel grades like 304 and 316. Grade 304 is ideal for general-purpose usage, while 316 offers higher resistance in marine or chemical environments. In high-load applications, alloy steel may be selected for added strength.
Manufacturing Process:
- Raw Material Inspection
- Heading (Cold Forging or Hot Forging based on size)
- Thread Rolling
- Drilling Safety Hole
- Washer Assembly (SEMS integration)
- Heat Treatment (if alloy steel)
- Surface Coating
- 100% Quality Inspection
- Standard or Custom Packaging
Each bolt is carefully crafted under tight quality controls and optimized for both performance and safety.
