Mechanical fixing components for accurate positioning and concealed clamping, sourcing map Ball Point Set Screws. Engineers and hobbyists gain reliable, slightly elastic locating that reduces surface wear. Are M5 spring-loaded grub screws precise and durable enough for regular workshop use?
⚡ At a Glance
- • Holding Force: Spring force 4.0 - 18N with a 1.1mm stroke for repeatable contact
- • Best for: Fixtures and machinery needing low-profile, adjustable locating and clamping
- • Not ideal for: Applications that require protruding fasteners or integrated hands-free features
Spring-loaded ball plunger assembly gives controlled, slightly elastic contact with a 1.1mm stroke. High carbon steel construction and a hexagon socket drive suit concealed installation and regular adjustments.
Accurate positioning - with a spring-loaded ball plunger
A spring, ball plunger and shell combine so the ball projects under controlled spring force, rated 4.0 to 18N, with a 1.1mm stroke. The spring evens out uneven loads by absorbing minor misalignment.
Repeatable locating of workpieces is possible without protruding ends, and slight movement is permitted without loosening, reducing surface damage.
Durable fastening - with high carbon steel construction
High carbon steel gives higher strength, hardness and wear resistance compared with softer steels. The hexagon socket drive spreads torque evenly across the head to reduce slippage during tightening.
Long service life under regular use and less risk of stripping when installing or adjusting in a workshop environment.
Compact, concealed installation - with M5 x 16mm sizing
Metric M5 thread at a 16mm length keeps the assembly compact so the head sits flush or concealed within housings. The small shell is designed so no protruding end is necessary for fixing.
Ideal where space is limited or where protruding fasteners would interfere with moving parts, especially when clamping non-parallel surfaces.
✨ The 4 Key Reasons for sourcing map Ball Point Set Screws
- High carbon steel - Extends service life under repeated contact and load
- Hexagon socket drive - Enables even torque, reduces risk of slippage during tightening
- Wide spring force range - Adapts to light to moderate loads for secure positioning
- Compact, concealed fit - Useful where protruding fasteners would interfere with function
