Shear Bolts Screw Set 19H1914 For John Deere Snow Blowers
The 19H1914 Shear Bolt Set combines Grade 5 shear bolts with M40333 nylon lock nuts. The 1/4″ diameter x 1″ long bolts feature a 7/8″ threaded section, providing stable performance under vibration and heavy use. This kit fits a range of John Deere snow blowers (46″, 47″, 50″, 54″) and is compatible with various riding lawn equipment. The nylon lock nut helps prevent loosening in harsh conditions, contributing to dependable field service in winter maintenance tasks.
100 Pcs M3-0.5 x 10mm High-Strength Torx Screws
These M3-0.5 x 10mm screws are Grade 10.9 alloy steel with a black oxide coating for durability and corrosion resistance. Included Torx Bit (T10) supports high-torque assembly while minimizing cam-out. The thread length is 10mm with a 5.7mm head diameter and 1.65mm head height, offering a compact yet strong fastener for precision electronics, small machinery, and DIY projects requiring reliable torque retention and fatigue resistance.
XunLiu Grade 10.9 Button Head Screws (M2X22)
These button head screws use Grade 10.9 alloy steel, heat-treated to provide exceptional tensile strength, reaching at least 150,000 psi. The internal hex socket drive (Allen) enables high-torque applications while preserving a low-profile appearance. They offer superior shear and tensile load resistance, making them well-suited for heavy-duty mechanical assemblies, automotive components, and structural connections where high strength and a clean finish are essential.
Twenty 1/4-20 Thumb Screws (Knurled, Made in USA)
These knurled thumb screws are designed for quick hand-tightening with a 1/4-20 UNC thread. The 1/2″ length plus the knurled round head provide easy installation and reusability in a variety of applications, including electronics enclosures and outdoor equipment housings. The screws are produced with alloy and stainless options, delivering practical corrosion resistance and reliable fastening without tools, particularly helpful for field maintenance.
No. 12 Stainless Truss Head Wood Screws (25 pc)
These No. 12 stainless steel truss head screws (25 pieces) are made from 18-8 (304) stainless steel, delivering excellent corrosion resistance and durability for indoor and outdoor wood projects. They feature a Type A point for easy penetration and secure fastening in woods and sheets. The plain finish and rust resistance make them suitable for decking, outdoor furniture, and garden structures where exposure to moisture is common.
8-Pack M12-1.75 x 40mm Flanged Hex Bolts
These 8-pack M12-1.75 x 40mm flanged hex bolts use Grade 10.9 high-tensile-strength alloy steel. The integrated flange with serrated underside reduces loosening under vibration, eliminating the need for washers in many mechanical joints. They are designed for heavy-duty automotive, machinery, and structural applications where high shear strength and reliable clamping are critical.
Fastenere Large Flange Pop Rivets
Note: While rivets aren’t screws, these large flange pop rivets provide high tensile and shear strength for rapid assembly in aluminum and similar materials. They feature a wide bearing surface to protect delicate components and a mandrel design that enhances performance. Use in metal fabrication, electronics enclosures, and outdoor metal-to-metal assemblies where rivet fastening is preferred for speed and uniform load distribution.
Buying Guide: Key Purchase Considerations And Comparisons
- Strength rating and material: For high shear resistance, prioritize Grade 10.9 or equivalent alloy steel, or stainless steel for corrosion resistance in outdoor or humid environments.
- Head design: Button heads and truss heads offer lower profile and increased surface area for distributing load, while knurled or flanged heads help resist loosening under vibration.
- Coatings: Black oxide, zinc, or stainless finishes reduce galling, corrosion, and wear during repeated assembly and disassembly.
- Drive type and torque: Torx and internal hex drives enable higher torque transfer and reduce cam-out, important for precision and heavy-duty fastening.
- Application environment: Outdoor, moisture-prone, or salt exposure requires corrosion-resistant materials (stainless steel). For indoor or controlled environments, standard alloy steels with protective coatings may suffice.
- Thread length and engagement: Ensure sufficient thread length for reliable engagement in the intended base material, avoiding under- or over-engagement that can reduce shear strength.
- Availability and packaging: For large projects, consider pack quantity, consistency of head dimensions, and compatibility with existing tools and bit types.
- Alternatives and combinations: In some cases, combining high-strength screws with locking nuts or thread-locking compounds can further reduce loosening under vibration.
